BACKGROUND OF THE INVENTION

The invention generally relates to nucleic acids and polypeptides encoded therefrom. More specifically, the invention relates to nucleic acids encoding cytoplasmic, nuclear, membrane bound, and secreted polypeptides, as well as vectors, host cells, antibodies, and recombinant methods for producing these nucleic acids and polypeptides.

SUMMARY OF THE INVENTION

The invention is based in part upon the discovery of nucleic acid sequences encoding polypeptides. The nucleic acids mad polypeptides are referred to herein as SEC1, SEC2, SEC3, SEC4, SEC5, SEC6, SEC7, SEC8, SEC9, SEC10, SEC11, and SEC12 nucleic acids and polypeptides. These nucleic acids and polypeptides, as well as derivatives, homologs, analogs and fragments thereof, will hereinafter be collectively designated as “SECX” nucleic acid or polypeptide sequences.

In one aspect, the invention provides an isolated SECX nucleic acid molecule encoding a SECX polypeptide that includes a nucleic acid sequence that has identity to the nucleic acids disclosed in SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23. In some embodiments, the SECX nucleic acid molecule will hybridize under stringent conditions to a nucleic acid sequence complementary to a nucleic acid molecule that includes a protein-coding sequence of a SECX nucleic acid sequence. The invention also includes an isolated nucleic acid that encodes a SECX polypeptide, or a fragment, homolog, analog or derivative thereof. For example, the nucleic acid can encode a polypeptide at least 80% identical to a polypeptide comprising the amino acid sequences encoded by SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23. The nucleic acid can be, for example, a genomic DNA fragment or a cDNA molecule that includes the nucleic acid sequence of any of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and23.

Also included in the invention is an oligonucleotide, e.g., an oligonucleotide which includes at least 6 contiguous nucleotides of a SECX nucleic acid (e.g., SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 2 1, and 23) or a complement of said oligonucleotide.

Also included in the invention are substantially purified SECX polypeptides (SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24). In certain embodiments, the SECX polypeptides include an amino acid sequence that is substantially identical to the amino acid sequence of a human SECX polypeptide.

The invention is also based in part upon the discovery of nucleic acid sequences encoding novel polypeptides. The novel nucleic acids and polypeptides are referred to herein as NOVX, or NOV1, NOV2, NOV3, NOV4, NOV5, NOV6, NOV7, and NOV8 nucleic acids and polypeptides. These nucleic acids and polypeptides, as well as derivatives, homologs, analogs and fragments thereof, will hereinafter be collectively designated as “NOVX” nucleic acid or polypeptide sequences.

In one aspect, the invention provides an isolated NOVX nucleic acid molecule encoding a NOVX polypeptide that includes a nucleic acid sequence that has identity to the nucleic acids disclosed in SEQ ID NOS:25, 27, 29, 31, 33, 35, 37 and 39. In some embodiments, the NOVX nucleic acid molecule will hybridize under stringent conditions to a nucleic acid sequence complementary to a nucleic acid molecule that includes a protein-coding sequence of a NOVX nucleic acid sequence. The invention also includes an isolated nucleic acid that encodes a NOVX polypeptide, or a fragment, homolog, analog or derivative thereof. For example, the nucleic acid can encode a polypeptide at least 80% identical to a polypeptide comprising the amino acid sequences of SEQ ID NOS:26, 28, 30, 32, 34, 36, 39 and 40. The nucleic acid can be, for example, a genomic DNA fragment or a cDNA molecule that includes the nucleic acid sequence of any of SEQ ID NOS:25, 27, 29, 31, 33, 35, 37 and 39.

If desired, the SECX and/or NOVX polypeptide can then be recovered.

In another aspect, the invention includes a method of detecting the presence of a SECX and/or NOVX polypeptide in a sample. In the method, a sample is contacted with a compound that selectively binds to the polypeptide under conditions allowing for formation of a complex between the polypeptide and the compound. The complex is detected, if present, thereby identifying the SECX and/or NOVX polypeptide within the sample.

The invention also includes methods to identify specific cell or tissue types based on their expression of a SECX and/or NOVX.

Also included in the invention is a method of detecting the presence of a SECX and/or NOVX nucleic acid molecule in a sample by contacting the sample with a SECX and/or NOVX nucleic acid probe or primer, and detecting whether the nucleic acid probe or primer bound to a SECX and/or NOVX nucleic acid molecule in the sample.

In a further aspect, the invention provides a method for modulating the activity of a SECX and/or NOVX polypeptide by contacting a cell sample that includes the SECX and/or NOVX polypeptide with a compound that binds to the SECX polypeptide in an amount sufficient to modulate the activity of said polypeptide. The compound can be. e.g., a small molecule, such as a nucleic acid, peptide, polypeptide, peptidomimetic, carbohydrate, lipid or other organic (carbon containing) or inorganic molecule, as further described herein.

The polynucleotides and polypeptides are used as immunogens to produce antibodies specific for the invention, and as vaccines. They are used to screen for potential agonist and antagonist compounds. For example, a cDNA encoding SECX may be useful in gene therapy, and SECX may be useful when administered to a subject in need thereof. By way of nonlimiting example, the compositions of the present invention will have efficacy for treatment of patients suffering the diseases and disorders listed above and/or other pathologies and disorders.

The invention further includes a method for screening for a modulator of disorders or syndromes including, e.g., diseases and disorders listed above and/or other pathologies and disorders and those disorders related to cell signal processing and metabolic pathway modulation.

Also within the scope of the invention is a method for screening for a modulator of activity, or of latency or predisposition to an disorders or syndromes including the diseases and disorders listed above and/or other pathologies and disorders or other disorders related to cell signal processing and metabolic pathway modulation by administering a test compound to a test animal at increased risk for the aforementioned disorders or syndromes. The test animal expresses a recombinant polypeptide encoded by a SECX nucleic acid. Expression or activity of SECX polypeptide is then measured in the test animal, as is expression or activity of the protein in a control animal which recombinantly-expresses SECX polypeptide and is not at increased risk for the disorder or syndrome. Next, the expression of SECX polypeptide in both the test animal and the control animal is compared. A change in the activity of SECX polypeptide in the test animal relative to the control animal indicates the test compound is a modulator of latency of the disorder or syndrome.

In yet another aspect, the invention includes a method for determining the presence of or predisposition to a disease associated with altered levels of a SECX polypeptide, a SECX nucleic acid, or both, in a subject (e.g., a human subject). The method includes measuring the amount of the SECX polypeptide in a test sample from the subject and comparing the amount of the polypeptide in the test sample to the amount of the SECX polypeptide present in a control sample. An alteration in the level of the SECX polypeptide in the test sample as compared to the control sample indicates the presence of or predisposition to a disease in the subject. Preferably, the predisposition includes diseases and disorders listed above and/or other pathologies and disorders. Also, the expression levels of the new polypeptides of the invention can be used in a method to screen for various cancers as well as to determine the stage of cancers.

In a further aspect, the invention includes a method of treating or preventing a pathological condition associated with a disorder in a mammal by administering to the subject a SECX polypeptide, a SECX nucleic acid, or a SECX-specific antibody to a subject (e.g., a human subject), in an amount sufficient to alleviate or prevent the pathological condition. In preferred embodiments, the disorder, includes the diseases and disorders listed above and/or other pathologies and disorders.

In yet another aspect, the invention can be used in a method to identity the cellular receptors and downstream effectors of the invention by any one of a number of techniques commonly employed in the art.

The disclosed sequence of SEC1 was derived by laboratory cloning of cDNA fragments, by in silico prediction of the sequence. The cDNA fragments covering either the full length of the DNA sequence, or part of the sequence, or both, were cloned. In silico prediction was based on sequences available in CuraGen's proprietary sequence databases or in the public human sequence databases, and provided either the full length DNA sequence, or some portion thereof.

The disclosed SEC1 of this invention maps to chromosome 1p22.3. Chromosome localization information was assigned using OMIM, the electronic northern bioinformatic tool implemented by CuraGen Corporation, public ESTs, public literature references and/or genomic clone homologies. This was executed to derive the chromosomal mapping of the SeqCalling assemblies, Genomic clones, literature references and/or EST sequences that were included in the invention.

The disclosed SEC1 polypeptide (SEQ ID NO:2) encoded by SEQ ID NO:1 has 381 amino acid residues, and is presented in Table 1B using the one-letter amino acid codes. The Psort profile for SEC1 predicts that this sequence has a signal peptide and is likely to be localized outside the cell with a certainty of 0.5422. In alternative embodiments, a SEC1 polypeptide is located to the endoplasmic reticulum (membrane) with a certainty of 0.1000, to the endoplasmic reticulum (lumen) with a certainty of 0.1000, or to lysosomes with a certainty of 0.1000. The Signal P predicts a likely cleavage site for a SEC1 peptide is between positions 24 and 25, i.e., at the dash in the sequence ALS-TC.

Public and proprietary sequence databases were searched for protein sequences with homology to SEC1 using BLASTP software. In all BLAST alignments herein, the “E-value” or “Expect” value is a numeric indication of the probability that the aligned sequences could have achieved their similarity to the BLAST query sequence by chance alone, within the database that was searched. The Expect value (E) is a parameter that describes the number of hits one can “expect” to see just by chance when searching a database of a particular size. It decreases exponentially with the Score (S) that is assigned to a match between two sequences of a database of comparable complexity. Essentially, the E value describes the random background noise that exists for matches between sequences.

The E value is used as a convenient way to create a significance threshold for reporting results. The default value used for blasting is typically set to 0.0001. In BLAST 2.0, the E value is also used instead of the P value (probability) to report the significance of matches. For example, an E value of one assigned to a hit can be interpreted as meaning that in a database of the current size one might expect to see one match with a similar score simply by chance. An E value of zero means that one would not expect to see any matches with a similar score simply by chance. See, e.g., http://www.ncbi.nlm.nih.gov/Education/BLASTinfo/. Occasionally, a string of X's or N's will result from a BLAST search. This is a result of automatic filtering of the query for low-complexity sequence that is performed to prevent artifactual hits. The filter substitutes any low-complexity sequence that it finds with the letter “N” in nucleotide sequence (e.g., “NNNNNNNNN”) or the letter “X” in protein sequences (e.g., “XXX”). Low-complexity regions can result in high scores that reflect compositional bias rather than significant position-by-position alignment (Wootton and Federhen, Methods Enzymol 266:554-571, 1996).

A BLAST analysis of SEC1 was run against the proprietary PatP GENESEQ Protein Patent database. The amino acid sequence of SEC1 has high homology to other proteins as shown in Table 1C.

In a search of public sequence databases, it was found for example, that the amino acid sequence of the protein of the invention was found to have 381 of 381 amino acid residues (100%) identical to the 381 amino acid CYR61 protein from Homo sapiens (NM_(—)001554 protein, E=1.3e−93).

Domain Analysis

The presence of identifiable domains in SEC1, as well as all other SECX proteins, was determined by searches using software algorithms such as PROSITE, DOMAIN, Blocks, Pfam, ProDomain, and Prints, and then determining the Interpro number by crossing the domain match (or numbers) using the Interpro website (http:www.ebi.ac.uk/interpro). DOMAIN results for SEC1 as disclosed in Table 1F, were collected from the Conserved Domain Database (CDD) with Reverse Position Specific BLAST analyses. This BLAST analysis software samples domains found in the Smart and Pfam collections. For Table 1F and all successive DOMAIN sequence alignments, fully conserved single residues are indicated by the sign (|) and “strong” semi-conserved residues are indicated by the sign (+). The “strong” group of conserved amino acid residues may be any one of the following groups of amino acids: STA, NEQK, NHQK, NDEQ, QHRK, MILV, MILF, HY, FYW.

Table 1F lists the domain description from DOMAIN analysis results against SEC 1. This indicates that the SEC1 sequence has properties similar to those of other proteins known to contain this domain.

CYR61 is a secreted, cysteine-rich, heparin-binding protein encoded by a growth factor-inducible immediate-early gene. Acting as an extracellular matrix-associated signaling molecule, CYR61 is an angiogemic inducer that promotes the adhesion of endothelial cells through interaction with integrins and augments growth factor-induced DNA synthesis in the same cell type (see, Expression of cyr61, a growth factor-inducible immediate-early gene. O'Brien TP, et al., Mol Cell Biol. 1990 July; 10(7):3569-77, incorporated by reference). CYR61 stimulates directed migration of human microvascular endothelial cells in culture through the alpha(V)beta(3)-dependent pathway and induces neovascularization of the surrounding tissues. Modulation of CYR61 provides for methods of treating disorders of angiogenesis. For example, specific anti-CYR61 antibodies are useful to block both the chemotactic and angiogenic activities of CYR61, and provide a method for detection of the CYR61 polypeptide in disease states, for example, in the detection and treatment of tumorigenesis. Upregulation or expression of CYR61 is useful to promote neovascularization, for example, to promote wound healing or in transplant grafts.

Through a proprietary technology designed to identify transcripts of all expressed genes, a cDNA designated CG55688-01 was isolated. In vitro, the recombinant protein was systematically tested in a number of endothelial cell assays and found to induce a critical process involved in the angiogellic cascade. First, CG55688-01 did not inhibit VEGF/bFGF-mediated proliferation or by itself induce endothelial proliferation. However, CG55688-01 significantly enhanced endothelial cell migration through enhanced matrix adhesion. These findings reveal a function for CG55688-01 as playing a role in a key process of angiogenesis. The molecule is a target for small molecules or antibodies as a cancer therapeutic or other diseases, such as psoriasis, for example, where inflammation is enhanced by increased vascularization. Alternatively, CG55688 is a therapeutic useful in wound healing, stroke or cardiovascular diseases.

Expression Purification and Biochemical Characterization of Recombinant SEC1

The CG55688-01 nucleic acid sequence disclosed as SEQ ID NO 1 was cloned into the pCEP4 vector (Invitrogen, Carlsbad, Calif.) and was transfected into HEK293T cells using Lipofectamine Plus reagent according to manufacturer's instructions (Life Technologies Inc., Rockville, Md.). The cell pellet and supernatant were harvested 72 h after transfection and examined for protein expression by Western blot analysis with an anti-V5 monoclonal antibody. After initial confirmation of expression, large-scale transfections were carried out in 150-cm² petri dishes using Lipofectamine Plus reagent. The conditioned medium was collected from the transfected cells after 72 h, pooled and loaded onto a Ni²⁺ affinity column according to manufacturer's instructions (Qiagen, Valencia, Calif.). The column was washed with 10 column volumes of PBS, pH 7.4 containing 500 mM NaCl. Non-specifically bound proteins were washed with above buffer containing 5 mM imidazole. The bound proteins were eluted with PBS, pH 7.4 containing 500 mM imidzaole. Peak fractions from the 500 mM imidazole peak were pooled and dialyzed overnight in PBS, pH 7.4. The protein was further purified by a second round of purification over a Ni²⁺ affinity column and dialyzed against PBS, pH 7.4. The concentration of protein was measured by the Bradford reagent (Bio-Rad, Hercules, Calif.). Protein purity was assessed by Coomassie Brilliant Blue staining after analysis by SDS-PAGE on a 4-15% Tris/glycine gradient gel. Purified CG55688-01 was also transferred to PVDF membrane and subsequently processed for 15 cycles of N-terminal sequence analysis. In addition, the purified protein was tested for endotoxin using the Gel clot method (Cape Cod Associates, CapeCod, Mass.) and found to have <10 EU/mg of protein. Subsequently, the purified protein was used in all in vitro angiogenesis assays.

Endothelial Cell BrdU Incorporation Assay

Purified CG55688-01 was tested for its ability to induce or inhibit the proliferation of endothelial cells using a BrdU incorporation assay. Proliferative activity is measured by treatment of serum-starved cultured cells with a given agent and measurement of BrdU incorporation during DNA synthesis. The proliferative and antiproliferative effect of CG55688-01 was assessed using HUVEC and HMVEC-d. Cells were seeded into wells at 4×10⁴ cells/well, were synchronized by serum starvation overnight in minimal medium (0.5% FBS) and stimulated with VEGF and bFGF at 10 ng/ml in the presence of 1% FBS. Different concentrations of purified protein were added along with VEGF, and incubated for 18 hours. BrdU was then added, a 4-hour incubation allowed, and ELISA was performed. The cells were plated in 96-well flat bottom plates pre-coated with Attachment Factor (Cascade Biologics, Portland, Oreg.) at 3×10⁴ cells/well in 100 μl of Medium 200 (Cascade Biologics, Portland, Oreg.) containing 0.5% FBS. After 24 hours of starvation at 37° C., the cells were washed twice with serum-free medium, and then fed with fresh medium containing 1% FBS with VEGF₁₆₅ and bFGF (10 ng/ml) (R & D Systems, Minneapolis, Minn.) with and without CG55688-01 protein. The cells were pulsed with BrdU for 4 hours before harvest. The BrdU assay was performed according to the manufacturer's specification (Roche Molecular Biochemicals, Indianapolis, Ind.).

Migration Assay

To determine the ability of recombinant CG55688-01 to block migration of HUVEC and HMVEC-d towards VEGF₁₆₅, 24-well transwell (BD Biosciences, Bedford, Mass.) migration chambers having an 8 μm pore size were used. The transwells were coated with 10 μg/ml of Type I collagen (BD Biosciences, Bedford. Mass.) from rat tail for 1 h at 37° C. After washing with PBS, the wells were seeded with HUVEC suspended at 2×10⁷ cells/ml in Medium 200 containing 1% BSA (Sigma Chemicals., St Louis, Mo.). The lower chambers (600 μl) were filled with Medium 200 containing 1% FBS supplemented with 10 ng/ml of recombinant VEGF₁₆₅ The upper chamber was seeded with 4×10⁴ cells/well in 200 μl containing different concentrations of CG55688-01. Cells were allowed to migrate for 4 h at 37° C. Following incubation, cells on the upper surface of the membrane (non-migrated cells) were scraped with a cotton swab. Cells on the lower side of the membrane (migrated cells) were stained with 0.2% Crystal Violet dye (Fisher Scientific, Springfield, N.J.) in 70% ethanol for 30 min The cells were then destained in PBS, pH 7.4 and the membrane was left to air dry at room temperature. The number of cells that had migrated was counted using a Zeiss Axiovert 100 inverted microscope at three independent areas and the mean number of migrated cells was calculated. RGD control peptide (Life Technologies Inc., Rockville, Md.) was used as a positive control for each experiment. The number of cells migrating in the presence or absence of CG55688-01 was counted in three independent fields. The number of cells migrated in the presence of 1% FBS with VEGF (10 ng/ml) was considered as maximum migration and the percentage of inhibition was calculated. The results demonstrate that CG55688-01 specifically affects migration of large and small vessel endothelial cells.

Endothelial Cell Adhesion Assay

Untreated 96-well flat bottom tissue culture plates (Fisher Scientific, Springfield, N.J.) were used in the cell adhesion assay. The plates were coated with 10 μg/ml of different extracellular matrix (ECM) proteins (Type I collagen, Type IV collagen, fibronectin, vitronectin, laminin and Matrigel) overnight at 4° C. The remaining protein binding sites were blocked with 1% BSA in PBS, pH 7.4 for 2 h at 37° C. HUVEC were grown to subconfluence (70-80%) in Medium 200. The cells were labeled with Calcein-AM fluorophore (Molecular Probes, Eugene, Oreg.) as described by the manufacturer. The cells were trypsinized, washed and resuspended at 1.5×10⁵ cells/ml in serum-free medium containing 1% BSA. The cells were then mixed with different concentrations of CG55688-01 or the absence of CG55688-01 in 100-μl volumes containing 2×10⁴ cells/treatment for 15 min at room temperature. After incubation, the cell suspension was then added to each well and the plates were incubated at 37° C. for 45 min in 5% CO₂ At the end of the incubation period, unattached cells were removed by washing 3 times with serum-free medium, and attached cells were counted using a Cytofluor 4000 flurometer (PE Applied Biosystems, Foster City, Calif.). The number of attached cells was represented as percentage of endothelial cell adhesion. Typically, greater than 90% of cells were labeled with Calcein AM fluorescence dye. In the presence of different concentrations of CG55688-01, there was a dose-enhancement of cell adhesion to ECM-coated plates indicating that CG55688-01 enhances endothelial cell adhesion to different ECM proteins, with the most pronounced effect observed on fibronectin and vitronectin.

Mesothelin, a cell-surface differentiation antigen, is a 40-kD GPI-linked (glycosylphosphatidylinositol) cell-surface glycoprotein, that is present on the surface of normal mesothelium and is overexpressed in many patients with cancer and malignant mesotheliomas. For example, mesothelin is a marker for pancreatic adenocarcinoma, ovarian cancer, pancreatic cancer, lung cancer, squamous cell carcinoma, and numerous other neoplastic cellular transformations as identified by gene expression analysis. Mesothelin overexpression in cancers has potential diagnostic, imaging, and therapeutic implications. Mesothelin is a antigen that is expressed in a highly tissue-specific manner. High level expression of the protein is seen in the mesothelium, and the tissue forming the pleural, pericardial, and peritoneal membranes. The gene contains an 1884-bp open reading frame encoded by 15 exons occupying 8 kb of human chromosome 16. An 1850-bp region of genomic DNA at the 5′ end of the gene encompassing the proposed transcriptional start site was also cloned. This region lacks a TATA box and other regulatory elements such as SP1 sites, which are commonly found in promoters. Transient transfection analyses demonstrated that mesothelium-specific control elements are present within the 1.85-kb region. Minimal constitutive promoter elements were localized to a 317-bp region. Tissue-specific enhancer elements upstream of the minimal promoter were found to activate transcription from the homologous and a heterologous promoter in a position- and orientation-independent manner.

TABLE 3E ClustalW Alignment of SEC3

MAP 17 and PDZK1 mRNAs are markedly up-regulated in human carcinomas. The MAP17 protein product is a 17-kd membrane-associated protein as determined by immunoprecipitation. MAP17 is expressed at significant levels in a the proximal tubular epithelial cells of the kidney, and is induced in immortalized breast ductal epithelial cell lines compared with normal breast ductal epithelial cells, and, in vivo, in premalignant conditions, such as adenoma of the colon and ductal carcinoma in situ of the breast. MAP17 is expressed abundantly in carcinomas arising from kidney, colon, lung, and breast, in some cases with a membrane-associated apical glandular distribution. In tissue culture, MAP17 was localized to the cell membrane in areas of cell-cell contact, i.e., the distribution of cell-function-associated proteins. Transfection of a full-length wild-type MAP17 cDNA clone into a colon carcinoma cell line, HT-29, markedly decreased cell proliferation in vitro and tumor growth in vivo.

The biological effects of epidermal growth factor (EGF) and transforming growth factor-alpha (TGF-alpha) are mediated by an interaction with a specific cell surface receptor having both intra- and extracellular domains. The structure of the intracellular domain can be closely aligned with retroviral protein tyrosine kinases. Upon ligand-binding there is a change in conformation of the extracellular domain, the receptor being converted to dimeric. Dimeric receptor has a higher rate of catalysis than monomeric and rapidly becomes phosphorylated. This form of the receptor now associates with and phosphorylates enzymes such as phospholipase-C, altering their catalytic activity and subcellular distribution. This system appears to stimulate the effects of epidermal growth factor receptor (EGFr) activation, notably proliferation, morphology, paracrine effects and differentation. Coexpression of transforming growth factor alpha (TGF-alpha) and its receptor epidermal growth factor receptor (EGFR) is known to be associated with aggressive biologic behavior and adverse clinical outcome in a variety of tumors, for example, pancreatic adenocarcinomas.

Neuronatin, disclosed herein as SEC5, is a brain-specific human gene isolated and observed to be selectively expressed during brain development. The human gene spans 3973 bases and contains three exons and two introns. Based on primer extension analysis, a single cap site is located 124 bases upstream from the methionine (ATG) initiation codon, in good context, GAACCATGG. The promoter contains a modified TATA box, CATAAA (−27), and a modified CAAT box, GGCGAAT (−59). The 5′-flanking region contains putative transcription factor binding sites for SP-1, AP-2 (two sites), delta-subunit, SRE-2, NF-A1, and ETS. In addition, a 21-base sequence highly homologous to the neural restrictive silence element that governs neuron-specific gene expression is observed at −421. Furthermore, SP-1 and AP-3 binding sites are present in intron 1. All splice donor and acceptor sites conformed to the GT/AG rule. Exon 1 encodes 24 amino acids, exon 2 encodes 27 amino acids, and exon 3 encodes 30 amino acids. At the 3′-end of the gene, the poly(A) signal, AATAAA, poly(A) site, and GT cluster are observed. The neuronatin gene is expressed as two mRNA species, alpha and beta, generated by alternative splicing. The alpha-form contains all three exons, whereas in the beta-form, the middle exon has been spliced out. The third nucleotide of all frequently used codons, except threonine, of neuronatin is either G or C, consistent with codon usage expected for Homo sapiens.

The human neuronatin gene on chromosome 20q11.2 is imprinted and transcribed specifically from the paternal allele. The region containing neuronatin has multiple CpG islands, and methylation analysis showed that a 1.8-kb CpG island in its promoter region exhibits differential methylation in all tissues examined. Neuronatin lies within the singular 8.5-kb intron of the gene encoding bladder cancer-associated protein (BLCAP). Northern blot analysis reveals that the human neuronatin message is expressed predominantly in the fetal brain in the brain-specific manner, but only faintly in the adult brain. Strong neuronatin expression is observed in the anterior pituitary gland, and in several human pituitary adenomas, including ACTH-producing, GH-producing, and nonfunctioning adenomas.

The SEC5 disclosed in this invention is expressed in at least the following tissues: apical microvilli of the retinal pigment epithelium, arterial (aortic), basal forebrain, brain, Burkitt lymphoma cell lines, corpus callosum, cardiac (atria and ventricle), caudate nucleus, CNS and peripheral tissue, cerebellum, cerebral cortex, colon, cortical neurogenic cells, endothelial (coronary artery and umbilical vein) cells, palate epithelia, eye, neonatal eye, frontal cortex, fetal hematopoietic cells, heart, hippocampus, hypothalamus, leukocytes, liver, fetal liver, lung, lung lymphoina cell lines, fetal lymphoid tissue, adult lymphoid tissue, those that express MHC I, II, and III, nervous tissues, medulla, subthalamic nucleus, ovary, pancreas, pituitary, placenta, pons, prostate, putamen, serum, skeletal muscle, small intestine, smooth muscle (coronary artery in aortia) spinal cord, spleen, stomach, taste receptor cells of the tongue, testis, thalamus, and thymus tissue.

Mechanisms for formation of drug dependence and expression of withdrawal syndrome have not fuilly clarified despite of huge accumulation of experimental and clinical data at present. Several clinical features of withdrawal syndrome are considered to be common among patients with drug dependence induced by different drugs of abuse. One of them is anxiety. Recent investigations have revealed that diazepam binding inhibitor (DBI), disclosed herein as SEC6 serves as an inverse agonist for benzodiazepine (BZD) receptors with endogenously anxiogenic potential. Cerebral DBI expression in brain participates in the formation of drug dependence and/or emergence of withdrawal syndrome. Cerebral DBI expression significantly increases in mammals with drug dependence induced by drugs such as, for example, morphine, nicotine, and alcohol. In the cases of nicotine- and morphine-dependent mice concomitant administration of antagonists for nicotinic acetylcholine and opioid receptors, respectively, abolished the increase. Abrupt cessation of administration of drugs facilitated further increase in DBI expression. Therefore, these alterations in DBI expression have close relationship with formation of drug dependence and/or emergence of withdrawal syndrome, and are considered to be a common biochemical process in drug dependence induced by different drugs of abuse. DBI, and the modulation of DBI expression and activity thus provides for therapeutic targets for common biochemical pathways involved in drug dependence and provides a method of preventing the formation of drug dependence and/or the emergence of withdrawal syndromes.

The aminopeptidase-N (a/k/a APN, CD13, EC 3.4.11.2) disclosed herein as SEC7, is a well established marker of normal and malignant cells of the myelo-monocytic lineage. It is also expressed by leukaemic blasts of a small group of patients suffering from acute or chronic lymphoid leukaemia. CD13/aminopeptidase N (E.C.3.4.11.2) is an ectoenzyme located in the outer membrane. A soluble, non-.cell-associated form of CD13/GP150/aminopeptidase-N localizable to plasma also exists.

The expression of the APN gene in T cell lines as well as the induction of APN gene and surface expression in human peripheral T cells by mitogenic activation have been demonstrated. For example, aminopeptidase expression was shown to be upregulated by a Th1-related cytokine, IFN-gamma. The induction of APN surface expression is partially resistent to the action of the inhibitors of protein biosynthesis, puromycin and cycloheximide, and is not prevented by tunicamycin, an inhibitor of glycosylation. The rapid mitogen-induced surface expression of APN, detectable 20 hours after stimulation, is dominated by mechanisms not dependent on de novo protein biosynthesis or glycosylation. Monocyte, granulocyte, and lymphocyte-enriched cell fractions possess aminopeptidase-N activity that is inhibitable by CD13 antibodies. Immunoaffinity isolation of plasma aminopeptidase-N has also been carried out; further characterization using functional studies and sodium dodecyl sulfate-polyacrylamide gel (SDS-PA,GE,) electrophoresis indicates that CD13 MABs can completely clear plasma of aminopeptidase-N activity and that the purified protein has similar electrophoretic characteristics to cell-derived material.

The activity of aminopeptidase in, for example, bronchoalveolar lavage fluid (BALF) was significantly higher in patients with sarcoidosis than in normal volunteers (NV) and control patients (CP). The activity significantly correlated with lymphocyte percentages and the ratio of CD4+ to CD8+ T lymphocytes in the BALF, and was higher in patients with sarcoidosis with parenchymal involvement than in those without the involvement. CD13/aminopeptidase N protein, which has a molecular mass of approximately 150 kD, was detectable in alveolar macrophages (AM) from patients with sarcoidosis at higher levels than in those from NV. CD13/aminopeptidase N induced in vitro chemotactic migration of human lymphocytes in a concentration range of 10(−)(5) to 10(−)(1) U/ml. The chemotactic activity was greater for CD4+ T lymphocytes than for CD8+ T lymphocytes. The enzymatic activity of CD13/aminopeptidase N was responsible for the chemotactic activity because bestatin, an inhibitor of CD13/aminopeptidase N, abolished the chemotactic activity. Higher chemotactic activity for lymphocytes was detected in the BALF from patients with sarcoidosis than in that from NV, and the activity was significantly decreased by treatment with bestatin. CD13/aminopeptidase N expressed in AM thus has a role in T-lymphocyte involvement in the sarcoid lung and the pathogenesis of alveolitis in this disorder and other disorders involving abberant cellular proliferation.

TFF-peptides (i.e. TFF1, TFF2, TFF3; formerly P-domain peptides, trefoil factors) have been established as secretory products typical of mucin-producing epithelial cells, for example, the respiratory tract, the salivary glands, the uterus, and the conjunctiva. TFF-peptides have a pivotal role in maintaining the surface integrity of these delicate epithelia as constituents of mucus gels as well as by their anti-apoptotic properties and their motogenic activity modulating cell migratory processes. Mucin-associated TFF-peptides (formerly P-domain peptides or trefoil factors) are typical motogens enhancing migration of cells in various in vitro models mimicking restitution of the intestine.

One of these peptides, TFF3, disclosed herein as SEC8 has been detected as a new neuropeptide of the human hypothalamo-pituitary axis where it is synthesized in oxytocinergic neurons of the paraventricular and supraoptic nuclei. From there it is transported to the posterior pituitary where it is released into the blood stream. Promoter methylation analyses showed that, in tissues where these genes are normally expressed, the proximal promoters of TFF1 and TFF2 are specifically not methylated and that of TFF3 is partially demethylated. In contrast, in organs that do not express TFFs, the promoters of the three genes are methylated. These findings strongly argue for the involvement of epigenetic mechanisms in the regulation of TFF expression in normal and pathological conditions. In addition, TFF3 demonstrates anti-anoikic properties. TFF3 activates NF-kappaB in enterocytes, and TFF3-induced resistance to anoikis in intestinal epithelial cells is mediated by a distinct signaling cascade linked to NF-kappaB.

Trefoil peptides are abundantly expressed epithelial cell products which exert protective effects and are key regulators of gastrointestinal epithelial restitution, the critical early phase of cell migration after mucosal injury. TFF-peptides act as motogens in the human respiratory epithelium triggering rapid repair of damaged mucosa in the course of airway diseases such as asthma. Synthesis of TFF-peptides also occurs pathologically as result to chronic inflammatory diseases, for example of the gastrointestinal tract. Aberrant synthesis of TFF-peptides is observed in many tumors, for example, TTF is induced in human intestinal metaplasia and conserved in all gastric cancers.

Lysophospholipase, disclosed herein as SEC9, is a critical enzyme that acta on biological membranes to regulate the multifunctional lysophospholipids. Increased levels of lysophospholipids are associated with a host of diseases. Low activity of key phospholipid catabolic and anabolic enzymes in human substantia nigra results in reduced ability to repair oxidative membrane damage, as may occur, for example, in Parkinson's disease and Alzheimer's disease. Lysophospholipase is a major autocrystallizing constituent of human eosinophils and basophils, comprising approximately 10% of the total cellular protein in these granulocytes. Identification of the distinctive hexagonal bipyramidal crystals of CLC protein in body fluids and secretions has long been considered a hallmark of eosinophil-associated allergic inflammation. The compositions for and methods of modulating lysophospholipase has utility in the prevention and treatment of allergic diseases and inflammation.

Carbonic anhydrases, disclosed as SEC10 herein. are proteins involved in the catalytic hydration of carbon dioxide to carbonic acid. There is increasing evidence that hypoxia-regulated gene expression influences tumor aggressiveness, contributing to the poorer outcome of patients with hypoxic tumors. The role of the transcriptional complex hypoxia-inducible factor-1 as an important mediator of hypoxia-regulated gene expression is one of the best documented pathways. Recently, it has emerged that certain tumor-associated carbonic anhydrases (CAs) can be added to the list of known hypoxia-inducible factor-responsive genes. CA expression in tumors with low vascularization defined a prognosis similar to the one of patients with highly angiogenic tumors. Multivariate analysis revealed that CA expression is a significant prognostic factor independent of angiogenesis. The expression of CA is linked to the expression of a constellation of proteins involved in angiogenesis, apoptosis inhibition, and cell-cell adhesion disruption, which explains the strong association of CA with poor outcome.

The SEC10 disclosed in this invention is expressed in at least the following tissues: apical microvilli of the retinal pigment epithelium, arterial (aortic), basal forebrain, brain, Burkitt lymphoma cell lines, corpus callosum, cardiac (atria and ventricle), caudate nucleus, CNS and peripheral tissue, cerebellum, cerebral cortex, colon, cortical neurogenic cells, endothelial (coronary artery and umbilical vein) cells, palate epithelia, eye, neonatal eye, frontal cortex, fetal hematopoietic cells, heart, hippocampus, hypothalamus, leukocytes, liver, fetal liver, lung, lung lymphoma cell lines, fetal lymphoid tissue, adult lymphoid tissue, those that express MHC I, II, and III, nervous tissues, medulla, subthalamic nucleus, ovary, pancreas, pituitary, placenta, pons, prostate, putamen, serum, skeletal muscle, small intestine, smooth muscle (coronary artery in aortia) spinal cord, spleen, stomach, taste receptor cells of the tongue, testis, thalamus, and thymus tissue. This information was derived by determining the tissue sources of the sequences that were included in the invention including but not limited to SeqCalling sources., public EST sources, literature sources, and/or RACE sources. Further expression data for SEC10 is provided in Example 2.

The nucleic acids and proteins of SEC10 are useful in potential therapeutic applications implicated in various SEC-related pathological disorders described further herein. The SEC10 nucleic acid encoding the carbonic anhydrase-like protein of the invention, or fragments thereof, may further be useful in diagnostic applications, wherein the presence or amount of the nucleic acid or the protein are to be assessed.

These antibodies may be generated according to methods known in the art, using prediction from hydrophobicity charts, as described in the “Anti-SECX Antibodies” section below. The disclosed SEC10protein has multiple hydrophilic regions, each of which can be used as an immunogen. In one embodiment, for example. a contemplated SEC10 epitope comprises from about amino acids 20 to about 100. In another embodiment, for example, a SEC10 epitope comprises from about amino acids 102 to about 160. In further embodiments, for example, a SEC10 epitope comprises from about 175 to about 290.

Frizzled (FZD) genes, disclosed herein as SEC11, encode receptors for WNTs, which play key roles in carcinogenesis and embryogenesis. Homologues of the N-terminal region of frizzled exist either as transmembrane or secreted molecules. The secreted frizzled related protein 2 (sFRP2) is upregulated within 2 days of in vitro development. In vivo sFRP2 expression was likewise found in mesenchymal condensates and subsequent epithelial structures. Detailed in situ hybridization analysis revealed sFRP2 expression during development of the eye, brain, neural tube, craniofacial mesenchyme, joints, testis, pancreas and below the epithelia of oesophagus, aorta and ureter where smooth muscles develop. In a comparative analysis, transcripts of the related sFRP1 and sFRP4 genes were frequently found in the same tissues as sFRP2 with their expression domains overlapping in some instances, but mutually exclusive in others. While sFRP1 is specifically expressed in the embryonic metanephros, eye, brain, teeth, salivary gland and small intestine, there is only weak expression of sFRP4 except for the developing teeth, eye and salivary gland. Nevertheless, sFRP genes play quite distinct roles in the morphogenesis of several organ systems.

The SEC11 disclosed in this invention is expressed in at least the following tissues: apical microvilli of the retinal pigment epithelium, arterial (aortic), basal forebrain, brain, Burkitt lymphoma cell lines, corpus callosum, cardiac (atria and ventricle), caudate nucleus, CNS and peripheral tissue, cerebellum, cerebral cortex, colon, cortical neurogenic cells, endothelial (coronary artery and umbilical vein) cells, palate epithelia, eye, neonatal eye, frontal cortex, fetal hematopoietic cells, heart, hippocampus, hypothalamus, leukocytes, liver, fetal liver, lung, lung lymphoma cell lines, fetal lymphoid tissue, adult lymphoid tissue, those that express MHC I, II, and III, nervous tissues, medulla, subthalamic nucleus, ovary, pancreas, pituitary, placenta, pons, prostate, putamen, serum, skeletal muscle, small intestine, smooth muscle (coronary artery in aortia) spinal cord, spleen, stomach, taste receptor cells of the tongue, testis, thalamus, and thymus tissue. This information was derived by determining the tissue sources of the sequences that were included in the invention including but not limited to SeqCalling sources, public EST sources, literature sources, and/or RACE sources. Further expression data for SEC11 is provided in Example 2.

The nucleic acids and proteins of SEC11 are useful in potential therapeutic applications implicated in various SEC-related pathological disorders described further herein. The SEC11 nucleic acid encoding, the FZD10-like protein of the invention, or fragments thereof, may further be useful in diagnostic applications, wherein the presence or amount of the nucleic acid or the protein are to be assessed.

These materials are further useful in the generation of antibodies that bind immunospecifically to the substances of the invention for use in therapeutic or diagnostic methods. These antibodies may be generated according to methods known in the art, using prediction from hydrophobicity charts, as described in the “Anti-SECX Antibodies” section below. The disclosed SEC11 protein has multiple hydrophilic regions, each of which can be used as an immunogen. In one embodiment, for example, a contemplated SEC11 epitope comprises from about amino acids 20 to about 85. In another embodiment, for example, a SEC11 epitope comprises from about amino acids 110 to about 200. In further embodiments, for example, a SEC11 epitope comprises from about 240 to about 260, from about 261 to about 290, from about 330 to 350, from about 420 to 430, from about 460 to 490, and about 520 to 581.

The homology between these and other sequences is shown graphically in the ClustalW analysis shown in Table 13D. In the ClustalW alignment of the NOV1 proteins, as well as all other ClustalW analyses herein, the black outlined amino acid residues indicate regions of conserved sequence (i.e., regions that may be required to preserve structural or functional properties), whereas non-highlighted amino acid residues are less conserved and can potentially be altered to a much broader extent without altering protein structure or function.

TABLE 13D ClustalW Analysis of NOV1

The presence of identifiable domains in NOV1, as well as all other NOVX proteins, was determined by searches using software algorithms such as PROSITE, DOMAIN, Blocks, Pfam, ProDomain, and Prints, and then determining the Interpro number by crossing the domain match (or numbers) using the Interpro website (http:www.ebi.ac.uk/interpro). DOMAIN results for NOV1 as disclosed in Tables 13K-13L, were collected from the Conserved Domain Database (CDD) with Reverse Position Specific BLAST analyses. This BLAST analysis software samples domains found in the Smart and Pfam collections. For Table 1K and all successive DOMAIN sequence alignments, fully conserved single residues are indicated by black shading or by the sign (|) and “strong” semi-conserved residues are indicated by grey shading or by the sign (+). The “strong” group of conserved amino acid residues may be any one of the following groups of amino acids: STA, NEQK, NHQK, NDEQ, QHRK, MILV, MILF, HY, FYW.

Tables 1E-F list the domain descriptions from DOMAIN analysis results against NOV1. This indicates that the NOV1 sequence has properties similar to those of other proteins known to contain this domain. Below are representative domain results. There are additional areas on NOV1a that also have homology to these Domains.

Estrogen responses of human breast cancer cell lines have frequently been shown to be promoted by insulin. The action of insulin, and its interaction with estradiol, regulates the expression of the estrogen-induced genes, LIV-1 and pS2. Both hormones cause increases in mRNA levels of the two genes but do so by distinct mechanisms. The concentration of insulin required to produce this effect suggests that it is acting via its ability to bind to the IGF-1 receptor. Both insulin and estradiol exert their effects at the level of transcription. Induction by insulin is dependent upon continued protein synthesis whereas induction by estradiol is not. Induction by both insulin and estradiol is prevented by the pure antiestrogen. ICI 164384, indicating the requirement for an activatable estrogen receptor. Insulin does not stimulate LIV-1 expression via the androgen receptor. These results demonstrate that both estradiol and insulin can stimulate the transcription of these estrogen-inducible genes, by separate mechanisms both of which involve the estrogen receptor. (See El-Tanani et al., 1997, J. Steroid Biochem Mol Biol. 60:269).

Investigation of the protein product of the estrogen-regulated gene LIV-1, implicated in metastatic breast cancer, has revealed 10 protein sequences of unknown function that belong to a new family with potential to control intracellular Zn2+ homeostasis. Sequence alignment highlights the similarity in transmembrane domains and extramembrane charged residues, indicating potential ton-transport ability. This family has a novel highly conserved motif of 66 residues, including a transmembrane domain and a catalytic zinc-binding sequence of zinc metalloproteases, containing conserved (indicated in bold type) proline and glutamine residues. These proteins contain more plentiful histidine-rich repeats than zinc transporters, suggesting an ability to bind or transport zinc across membranes. These 11 proteins may form a new family with the potential to control intracellular Zn2+ homeostasis. (See Taylor, 2000, IUBMB Life, 49:249).

Table 14E lists the domain description from DOMAIN analysis results against NOV2. This indicates that the NOV2 sequence has properties similar to those of other proteins known to contain this domain.

N-arginine dibasic convertase (NRD convertase) (accession number 1.27124) is a metalloendopeptidase from rat brain cortex and testis which cleaves peptide substrates on the N-terminus of arginine residues in basic doublets. Its predicted amino acid sequence contains a putative zinc binding motif in a region which exhibits 35% and 48% similarity with E coli protease III (pitrilysin E.C 3.4.99.44) and rat or human insulinase (E.C 3.4.99.45) respectively. This feature clearly classifies this endopeptidase as a member of the pitrilysin family of zinc-metalloproteases. However, the NRD convertase sequence contains a distinctive additional feature consisting of a 71 acidic amino acid stretch. Its substrate selectivity and the characteristic motifs of its amino acid sequence allow us to propose this new metalloendopeptidase as the first member of a new class of processing enzymes. (See Chesneau et al., 1994, Biochimie 76:234).

Heparin-binding epidermal growth factor-like growth factor (HB-EGF), a mitogen and chemotactic factor, binds to two receptor tyrosine kinases, erbB1 and erbB4. Now we demonstrate that HB-EGF also binds to a novel 140 kDa receptor on MDA-MB 453 cells. Purification of this receptor showed it to be identical to N-arginine dibasic convertase (NRDc), a metalloendopeptidase of the M16 family. Binding to cell surface NRDc and NRDc in solution was highly specific for HB-EGF among EGF family members. When overexpressed in cells, NRDc enhanced their migration in response to HB-EGF but not to EGF. Conversely, inhibition of endogenous NRDc expression in cells by antisense morpholino oligonucleotides inhibited HB-EGF-induced cell migration. Anti-erbB1 neutralizing antibodies completely abrogated the ability of NRDc to enhance HB-EGF-dependent migration, demonstrating that this NRDc activity was dependent on erbB1 signaling. Although NRDc is a metalloproteinase, enzymatic activity was not required for HB-EGF binding or enhancement of cell migration; neither did NRDc cleave HB-EGF. Together, these results suggest that NRDc is a novel specific receptor for HB-EGF that modulates HB-EGF-induced cell migration via erbB1. (See Nishi et al., 2001, EMBO J 20:3342).

The human tissue kallikrein gene family was, until recently, thought to consist of only three genes. Two of these human kallikreins, prostate-specific antigen and human glandular kallikrein 2, are currently used as valuable biomarkers of prostatic carcinoma. More recently, new kallikrein-like genes have been discovered. It is now clear that the human tissue kallikrein gene family contains at least 15 genes. All genes share important similarities, including mapping at the same chromosomal locus (19q13.4), significant homology at both the nucleotide and protein level, and similar genomic organization. All genes encode for putative serine proteases and most of them are regulated by steroid hormones. Recent data suggest that at least a few of these kallikrein genes are connected to malignancy.

TABLE 16F ClustalW Analysis of NOV4a

The development of refractory disease in acute myeloid or lymphoblastic leukaemias (AML, ALL) and multiple myeloma (MM) is frequently associated with the expression of one or several multidrug resistance (MDR) genes. MDR1, MRP1 and LRP have been identified as important adverse prognostic factors in AML, T-ALL and MM. Recently, it has become possible to reverse clinical multidrug resistance by blocking P-glycoprotein-mediated drug efflux. (See Sonneveld, 2000, J. Intern Med, 247:521).

A key issue in the treatment of acute leukemia is the development of resistance to chemotherapeutic drugs. Several mechanisms may account for this phenomenon, including failure of the cell to undergo apoptosis in response to chemotherapy, or failure of the drug to reach and/or affect its intracellular target. This review focuses on the latter mechanism, and on intracellular drug transport resistance mechanisms in particular. Expression of the ATP-binding cassette (ABC) transporter P-glycoprotein (Pgp) has generally been reported to correlate with prognosis in acute myeloid leukemia (AML). Additionally, but more controversial, expression of the ABC transporter multidrug resistance protein (MRP) and the vault-transporter lung resistance protein (LRP) have been correlated with outcome in AML. Despite these findings, functional efflux assays indicate the presence of non-Pgp, non-MRP transporters in AML. Recently, a novel ABC transporter, breast cancer resistance protein (BCRP) was cloned and sequenced in our laboratory. Transfection and overexpression of BCRP in drug-sensitive cells confers drug-resistance to the cells. BCRP is a half-transporter, and may homodimerize or form heterodimers (with a yet unknown half-transporter) to produce an active transport complex. Relatively high expression of BCRP mRNA is observed in approximately 30% of AML cases, suggesting a potential role for this new transporter in drug resistance in leukemia. (See Ross, 2000, Leukemia 14:467).

There are two mechanisms for glucose transport across cell membranes. In the intestine and renal proximal tubule, glucose is transported against a concentration gradient by a secondary active transport mechanism in which glucose is cotransported with sodium ions. In all other cells, glucose transport is mediated by one or more of the members of the closely related GLUT family of glucose transporters. The pattern of expression of the GLUT transporters in different tissues is related to the different roles of glucose metabolism in different tissues. Primary defects in glucose transport all appear to be extremely rare and not all possible deficiencies have been identified. Deficiency of the secondary active sodium/glucose transporters result in glucose/galactose malabsorption or congenital renal glycosuria. GLUT1 deficiency produces a seizure disorder with low glucose concentration in cerebrospinal fluid and GLUT2 deficiency is the basis of the Fanconi-Bickel syndrome, which resembles type I glycogen storage disease. (See Brown, 2000, J Inherit Metab Dis 23(3):237).

Epithelial cell differentiation and morphogenesis are crucial in many aspects of metazoan development. Recent genetic studies in Drosophila have revealed that the conserved Jun amino-terminal kinase (JNK) signaling pathway regulates epithelial morphogenesis during the process of embryonic dorsal closure and participates in the control of planar polarity in several tissues. Importantly, these studies have linked the JNK pathway to the decapentaplegic and Frizzled pathways in these processes, suggesting a high degree of integrative signaling during epithelial morphogenesis. (See Noselli et al., 1999, Curr Opin Genet Dev 9:466-72).

The wnt signaling pathway has important functions in nervous system development. To better understand this process we have cloned and analyzed the expression of the wnt receptor, frizzled 9, in the developing nervous system in mouse, chick and zebrafish. The earliest expression of mouse frizzled 9 mRNA expression begins at E8.5 with expression throughout the entire rostral-caudal neuraxis. This early expression pattern within the neural tube appears to be conserved between chick and zebrafish. Expression becomes restricted to a ventral domain in the mouse ventricular zone at E11.5, a region specified to give rise to neurons and glia. Using a polyclonal antibody to MFZ9 further shows expression limited to neural restricted precursors cells. (See Van Ray et al., 2001, Dev Genes Evol, 211(8-9):453-7).

The disclosed NOV6 nucleic acid of the invention encoding a Frizzled-9-like protein includes the nucleic acid whose sequence is provided in Table 18A or a fragment thereof.

The invention further includes nucleic acids whose sequences are complementary to those just described, including nucleic acid fragments that are complementary to any of the nucleic acids just described. The invention additionally includes nucleic acids or nucleic acid fragments, or complements thereto, whose strictures include chemical modifications. Such modifications include, by way of nonlimiting example, modified bases, and nucleic acids whose sugar phosphate backbones are modified or derivatized. These modifications are carried out at least in part to enhance the chemical stability of the modified nucleic acid, such that they may be used, for example, as antisense binding nucleic acids in therapeutic applications in a subject. In the mutant or variant nucleic acids, and their complements, up to about 5 percent of the bases may be so changed.

The disclosed NOV6 protein of the invention includes the Frizzled-9-like protein whose sequence is provided in Table 18B. The invention also includes a mutant or variant protein any of whose residues may be changed from the corresponding residue shown in Table 18B while still encoding a protein that maintains its Frizzled-9-like activities and physiological functions, or a functional fragment thereof. In the mutant or variant protein, up to about 5 percent of the residues may be so changed.

Prominin is the first identified member of a novel family of polytopic membrane proteins conserved throughout the animal kingdom. It has an unusual membrane topology, containing five transmembrane domains and two large glycosylated extracellular loops. In mammals, prominin is expressed in various embryonic and adult epithelial cells, as well as in nonepithelial cells, such as hematopoietic stem cells. At the subcellular level, prominin is selectively localized in microvilli and other plasma membrane protrusions, irrespective of cell type. At the molecular level prominin specifically interacts with membrane cholesterol and is a marker of a novel type of cholesterol-based lipid ‘raft’. A frameshift mutation in the human prominin gene, which results in a truncated protein that is no longer transported to the cell surface, is associated with retinal degeneration. Given that prominin is concentrated in the plasma membrane evaginations at the base of the outer segment of rod photoreceptor cells which are essential precursor structures in the biogenesis of photoreceptive disks, it is proposed that prominin has a role in the generation of plasma membrane protrusions, their lipid composition and organization and their membrane-to-membrane interactions. (See Corbeil et al., 2001, Traffic 2(2):32-91).

Hepsin is a type II transmembrane serine protease abundantly expressed on the surface of hepatocytes. Biochemical studies have shown that hepsin is an enzyme of 51 kDa with the trypsin-like substrate specificity. Several in vitro studies have suggested that hepsin may play a role in blood coagulation, hepatocyte growth, and fertilization. To determine the functional importance of hepsin, hepsin-deficient mice were generated by homologous recombination. Homozygous hepsin-/-mice were viable and fertile, and grew normally. When analyzed in hemostasis assays, such as tail bleeding time and plasma clotting times, and in vivo modes, such as disseminated intravascular coagulation, septic shock, and acute liver regeneration, hepsin-/-mice had similar phenotypes as wild-type controls. Liver weight and serum concentrations of liver-derived proteins or enzymes were also similar in hepsin-/- and wild-type mice. No abnormalities were identified in major organs in hepsin-/-mice in histological examinations. These results indicate that hepsin is not an essential enzyme for normal hemostasis, embryogenesis, and maintenance of normal liver function. Unexpectedly, serum concentrations of bone-derived alkaline phosphatase were approximately two-fold higher in both male and female hepsin-/-mice than those in wild-type controls. The underlying mechanism for this phenotype and long-term effects of hepsin deficiency remain to be determined. (See Wu, 2001, Front Biosci 1; 6:D192-200).

In the mutant or variant nucleic acids, and their complements, up to about 0 percent of the bases may be so changed.

These novel proteins can be used in assay systems for functional analysis of various human disorders, which will help in understanding of pathology of the disease and development of new drug targets for various disorders.

SECX and/or NOVX Nucleic Acids and Polypeptides

One aspect of the invention pertains to isolated nucleic acid molecules that encode SECX and/or NOVX polypeptides or biologically active portions thereof. Also included in the invention are nucleic acid fragments sufficient for use as hybridization probes to identify SECX and/or NOVX-encoding nucleic acids (e.g., SECX and/or NOVX mRNAs) and fragments for use as PCR primers for the amplification and/or mutation of SECX and/or NOVX nucleic acid molecules. As used herein, the term “nucleic acid molecule” is intended to include DNA molecules (e.g., cDNA or genomic DNA), RNA molecules (e.g., mRNA), analogs of the DNA or RNA generated using nucleotide analogs, and derivatives, fragments and homologs thereof The nucleic acid molecule may be single-stranded or double-stranded, but preferably is comprised double-stranded DNA.

An SECX and/or NOVX nucleic acid can encode a mature SECX and/or NOVX polypeptide. As used herein, a “mature” form of a polypeptide or protein disclosed in the present invention is the product of a naturally occurring polypeptide or precursor form or proprotein. The naturally occurring polypeptide precursor or proprotein includes, by way of nonlimiting example, the full-length gene product, encoded by the corresponding gene, Alternatively, it may be defined as the polypeptide, precursor or proprotein encoded by an ORF described herein. The product “mature” form arises, again by way of nonlimiting example, as a result of one or more naturally occurring processing steps as they may take place within the cell, or host cell, in which the gene product arises. Examples of such processing steps leading to a “mature” form of a polypeptide or protein include the cleavage of the N-terminal methionine residue encoded by the initiation codon of an ORF, or the proteolytic cleavage of a signal peptide or leader sequence. Thus a mature form arising from a precursor polypeptide or protein that has residues 1 to N, where residue 1 is the N-terminal methionine, would have residues 2 through N remaining after removal of the N-terminal methionine. Alternatively, a mature form arising from a precursor polypeptide or protein having residues 1 to N, in which an N-terminal signal sequence from residue 1 to residue M is cleaved, would have the residues from residue M+1 to residue N remaining. Further as used herein, a “mature” form of a polypeptide or protein may arise from a step of post-translational modification other than a proteolytic cleavage event. Such additional processes include, by way of non-limiting example, glycosylation, myristoylation or phosphorylation. In general, a mature polypeptide or protein may result from the operation of only one of these processes, or a combination of any of them.

The term “probes”, as utilized herein, refers to nucleic acid sequences of variable length, preferably between at least about 10 nucleotides (nt), 100 nt, or as many as approximately, e.g., 6,000 nt, depending upon the specific use. Probes are used in the detection of identical, similar, or complementary nucleic acid sequences. Longer length probes are generally obtained from a natural or recombinant source, are highly specific, and much slower to hybridize than shorter-length oligomer probes. Probes may be single- or double-stranded and designed to have specificity in PCR, membrane-based hybridization technologies, or ELISA-like technologies.

The term “isolated” nucleic acid molecule, as utilized herein, is one, which is separated from other nucleic acid molecules which are present in the natural source of the nucleic acid. Preferably, an “isolated” nucleic acid is free of sequences which naturally flank the nucleic acid (i.e., sequences located at the 5′- and 3′-termini of the nucleic acid) in the genomic DNA of the organism from which the nucleic acid is derived. For example, in various embodiments, the isolated SECX and/or NOVX nucleic acid molecules can contain less than about 5 kb. 4 kb, 3 kb, 2 kb, 1 kb, 0.5 kb or 0.1 kb of nucleotide sequences which naturally flank the nucleic acid molecule in genomic DNA of the cell/tissue from which the nucleic acid is derived (e g., brain, heart, liver, spleen. etc.). Moreover, an “isolated” nucleic acid molecule, such as a cDNA molecule, can be substantially free of other cellular material or culture medium when produced by recombinant techniques, or of chemical precursors or other chemicals when chemically synthesized.

A nucleic acid molecule of the invention, e.g., a nucleic acid molecule having the nucleotide sequence SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, or a complement of this aforementioned nucleotide sequence, can be isolated using standard molecular biology techniques and the sequence information provided herein. Using all or a portion of the nucleic acid sequence of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39 as a hybridization probe, SECX and/or NOVX molecules can be isolated using standard hybridization and cloning techniques (e.g., as described in Sambrook, et al., (eds.), MOLECULAR CLONING: A LABORATORY MANUAL 2^(nd) Ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989; and Ausubel, et al., (eds.), CURRENT PROTOCOLS IN MOLECULAR BIOLOGY, John Wiley & Sons, New York, N.Y., 1993.)

A nucleic acid of the invention can be amplified using cDNA, mRNA or alternatively, genomic DNA, as a template and appropriate oligonucleotide primers according to standard PCR amplification techniques. The nucleic acid so amplified can be cloned into an appropriate vector and characterized by DNA sequence analysis. Furthermore, oligonucleotides corresponding to SECX and/or NOVX nucleotide sequences can be prepared by standard synthetic techniques, e.g., using an automated DNA synthesizer.

As used herein, the term “oligonucleotide” refers to a series of linked nucleotide residues, which oligonucleotide has a sufficient number of nucleotide bases to be used in a PCR reaction. A short oligonucieotide sequence may be based on, or designed from, a genomic or cDNA sequence and is used to amplify, confirm, or reveal the presence of an identical, similar or complementary DNA or RNA in a particular cell or tissue. Oligonucleotides comprise portions of a nucleic acid sequence having about 10 nt, 50 nt, or 100 nt in length, preferably about 15 nt to 30 nt in length. In one embodiment of the invention, an oligonucleotide comprising a nucleic acid molecule less than 100 nt in length would further comprise at least 6 contiguous nucleotides SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, or a complement thereof. Oligonucleotides may be chemically synthesized and may also be used as probes.

In another embodiment, an isolated nucleic acid molecule of the invention comprises a nucleic acid molecule that is a complement of the nucleotide sequence shown in SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, or a portion of this nucleotide sequence (e.g., a fragment that can be used as a probe or primer or a fragment encoding a biologically-active portion of an SECX and/or NOVX polypeptide). A nucleic acid molecule that is complementary to the nucleotide sequence shown SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 or 39 is one that is sufficiently complementary to the nucleotide sequence shown SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 or 39 that it can hydrogen bond with little or no mismatches to the nucleotide sequence shown SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, thereby forming a stable duplex.

As used herein, the term “complementary” refers to Watson-Crick or Hoogsteen base pairing between nucleotides unit; of a nucleic acid molecule, and the term “binding” means the physical or chemical interaction between two polypeptides or compounds or associated polypeptides or compounds or combinations thereof. Binding includes ionic, non-ionic, van der Waals, hydrophobic interactions, and the like. A physical interaction can be either direct or indirect. Indirect interactions may be through or due to the effects of another polypeptide or compound. Direct binding refers to interactions that do not take place through, or due to, the effect of another polypeptide or compound, but instead are without other substantial chemical intermediates.

Fragments provided herein are defined as sequences of at least 6 (contiguous) nucleic acids or at least 4 (contiguous) amino acids, a length sufficient to allow for specific hybridization in the case of nucleic acids or for specific recognition of an epitope in the case of amino acids, respectively, and are at most some portion less than a full length sequence. Fragments may be derived from any contiguous portion of a nucleic acid or amino acid sequence of choice. Derivatives are nucleic acid sequences or amino acid sequences formed from the native compounds either directly or by modification or partial substitution. Analogs are nucleic acid sequences or amino acid sequences that have a structure similar to, but not identical to, the native compound but differs from it in respect to certain components or side chains. Analogs may be synthetic or from a different evolutionary origin and may have a similar or opposite metabolic activity compared to wild type. Homologs are nucleic acid sequences or amino acid sequences of a particular gene that are derived from different species.

Derivatives and analogs may be full length or other than full length, if the derivative or analog contains a modified nucleic acid or amino acid, as described below. Derivatives or analogs of the nucleic acids or proteins of the invention include, but are not limited to, molecules comprising regions that are substantially homologous to the nucleic acids or proteins of the invention, in various embodiments, by at least about 70%, 80%, or 95% identity (with a preferred identity of 80-95%) over a nucleic acid or amino acid sequence of identical size or when compared to an aligned sequence in which the alignment is done by a computer homology program known in the art, or whose encoding nucleic acid is capable of hybridizing to the complement of a sequence encoding the aforementioned proteins under stringent, moderately stringent, or low stringent conditions. See e.g. Ausubel, et al., CURRENT PROTOCOLS IN MOLECULAR BIOLOGY, John Wiley & Sons, New York, N.Y., 1993, and below.

A “homologous nucleic acid sequence” or “homologous amino acid sequence,” or variations thereof, refer to sequences characterized by a homology at the nucleotide level or amino acid level as discussed above. Homologous nucleotide sequences encode those sequences coding for isoforms of SECX and/or NOVX polypeptides. Isoforms can be expressed in different tissues of the same organism as a result of, for example, alternative splicing of RNA. Alternatively, isoforms can be encoded by different genes. In the invention, homologous nucleotide sequences include nucleotide sequences encoding for an SECX and/or NOVX polypeptide of species other than humans, including, but not limited to: vertebrates, and thus can include, e.g., frog, mouse, rat, rabbit, dog, cat, cow, horse, and other organisms. Homologous nucleotide sequences also include, but are not limited to, naturally occurring allelic variations and mutations of the nucleotide sequences set forth herein. A homologous nucleotide sequence does not, however, include the exact nucleotide sequence encoding human SECX and/or NOVX protein. Homologous nucleic acid sequences include those nucleic acid sequences that encode conservative amino acid substitutions (see below) in SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, as well as a polypeptide possessing SECX and/or NOVX biological activity. Various biological activities of the SECX and/or NOVX proteins are described below.

An SECX and/or NOVX polypeptide is encoded by the open reading frame (“ORF”) of an SECX and/or NOVX nucleic acid. An ORF corresponds to a nucleotide sequence that could potentially be translated into a polypeptide. A stretch of nucleic acids comprising an ORF is uninterrupted by a stop codon. An ORF that represents the coding sequence for a full protein begins with an ATG “start” codon and terminates with one of the three “stop” codons, namely, TAA, TAG, or TGA. For the purposes of this invention, an ORF may be any part of a coding sequence, with or without a start codon, a stop codon, or both. For an ORF to be considered as a good candidate for coding for a bona fide cellular protein, a minimum size requirement is often set, e.g., a stretch of DNA that would encode a protein of 50 amino acids or more.

The nucleotide sequences determined from the cloning of the human SECX and/or NOVX genes allows for the generation of probes and primers designed for use in identifying and/or cloning SECX and/or NOVX homologues in other cell types, e.g. from other tissues, as well as SECX and/or NOVX homologues from other vertebrates. The probe/primer typically comprises substantially purified oligonucleotide. The oligonucleotide typically comprises a region of nucleotide sequence that hybridizes under stringent conditions to at least about 12, 25, 50, 100, 150, 200, 250, 300, 350 or 400 consecutive sense strand nucleotide sequence SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 or 39; or an anti-sense strand nucleotide sequence of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 or 39; or of a naturally occurring mutant of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39.

Probes based on the human SECX and/or NOVX nucleotide sequences can be used to detect transcripts or genomic sequences encoding the same or homologous proteins. In various embodiments, the probe further comprises a label group attached thereto, e.g. the label group can be a radioisotope, a fluorescent compound, an enzyme, or an enzyme co-factor. Such probes can be used as a part of a diagnostic test kit for identifying cells or tissues which mis-express an SECX and/or NOVX protein, such as by measuring a level of an SECX and/or NOVX-encoding nucleic acid in a sample of cells from a subject e.g., detecting SECX and/or NOVX mRNA levels or determining whether a genomic SECX and/or NOVX gene has been mutated or deleted.

“A polypeptide having a biologically-active portion of an SECX and/or NOVX polypeptide” refers to polypeptides exhibiting activity similar, but not necessarily identical to, an activity of a polypeptide of the invention, including mature forms, as measured in a particular biological assay, with or without dose dependency. A nucleic acid fragment encoding a “biologically-active portion of SECX and/or NOVX” can be prepared by isolating a portion SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 or 39, that encodes a polypeptide having an SECX and/or NOVX biological activity (the biological activities of the SECX and/or NOVX proteins are described below), expressing the encoded portion of SECX and/or NOVX protein (e.g., by recombinant expression in vitro) and assessing the activity of the encoded portion of SECX and/or NOVX.

SECX and/or NOVX Nucleic Acid and Polypeptide Variants

The invention further encompasses nucleic acid molecules that differ from the nucleotide sequences shown in SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39 due to degeneracy of the genetic code and thus encode the same SECX and/or NOVX proteins as that encoded by the nucleotide sequences shown in SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39. In another embodiment, an isolated nucleic acid molecule of the invention has a nucleotide sequence encoding a protein having an amino acid sequence shown in SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40.

In addition to the human SECX and/or NOVX nucleotide sequences shown in SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, it will be appreciated by those skilled in the art that DNA sequence polymorphisms that lead to changes in the amino acid sequences of the SECX and/or NOVX polypeptides may exist within a population (e.g., the human population). Such genetic polymorphism in the SECX and/or NOVX genes may exist among individuals within a population due to natural allelic variation. As used herein, the terms “gene” and “recombinant gene” refer to nucleic acid molecules comprising an open reading frame (ORF) encoding an SECX and/or NOVX protein, preferably a vertebrate SECX and/or NOVX protein. Such natural allelic variations can typically result in 1-5% variance in the nucleotide sequence of the SECX and/or NOVX genes. Any and all such nucleotide variations and resulting amino acid polymorphisms in the SECX and/or NOVX polypeptides, which are the result of natural allelic variation and that do not alter the functional activity of the SECX and/or NOVX polypeptides, are intended to be within the scope of the invention.

Moreover, nucleic acid molecules encoding SECX and/or NOVX proteins from other species, and thus that have a nucleotide sequence that differs from the human SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39 are intended to be within the scope of the invention. Nucleic acid molecules corresponding to natural allelic variants and homologues of the SECX and/or NOVX cDNAs of the invention can be isolated based on their homology to the human SECX and/or NOVX nucleic acids disclosed herein using the human cDNAs, or a portion thereof, as a hybridization probe according to standard hybridization techniques under stringent hybridization conditions.

Accordingly, in another embodiment, an isolated nucleic acid molecule of the invention is at least 6 nucleotides in length and hybridizes under stringent conditions to the nucleic acid molecule comprising the nucleotide sequence of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39. In another embodiment, the nucleic acid is at least 10, 25, 50, 100, 250, 500, 750, 1000, 1500, or 2000 or more nucleotides in length. In yet another embodiment, an isolated nucleic acid molecule of the invention hybridizes to the coding region. As used herein, the term “hybridizes under stringent conditions” is intended to describe conditions for hybridization and washing under which nucleotide sequences at least 60% homologous to each other typically remain hybridized to each other.

Homologs (i.e., nucleic acids encoding SECX and/or NOVX proteins derived from species other than human) or other related sequences (e.g., paralogs) can be obtained by low, moderate or high stringency hybridization with all or a portion of the particular human sequence as a probe using methods well known in the art for nucleic acid hybridization and cloning.

As used herein, the phrase “stringent hybridization conditions” refers to conditions under which a probe, primer or oligonucleotide will hybridize to its target sequence, but to no other sequences. Stringent conditions are sequence-dependent and will be different in different circumstances. Longer sequences hybridize specifically at higher temperatures than shorter sequences. Generally, stringent conditions are selected to be about 5° C. lower than the thermal melting point (Tm) for the specific sequence at a defined ionic strength and pH. The Tm is the temperature (under defined ionic strength, pH and nucleic acid concentration) at which 50% of the probes complementary to the target sequence hybridize to the target sequence at equilibrium. Since the target sequences are generally present at excess, at Tm, 50% of the probes are occupied at equilibrium. Typically, stringent conditions will be those in which the salt concentration is less than about 1.0 M sodium ion, typically about 0.01 to 1.0 M sodium ion (or other salts) at pH 7.0 to 8.3 and the temperature is at least about 30° C. for short probes, primers or oligonucleotides (e.g., 10 nt to 50 nt) and at least about 60° C. for longer probes, primers and oligonucleotides. Stringent conditions may also be achieved with the addition of destabilizing agents, such as formamide.

Stringent conditions are known to those skilled in the art and can be found in Ausubel, et al., (eds.), CURRENT PROTOCOLS IN MOLECULAR BIOLOGY, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6. Preferably, the conditions are such that sequences at least about 65%, 70%, 75%, 85%, 90%, 95%, 98%, or 99% homologous to each other typically remain hybridized to each other. A non-limiting example of stringent hybridization conditions are hybridization in a high salt buffer comprising 6×SSC, 50 mM Tris-HCl (pH 7.5), 1 mM EDTA, 0.02% PVP, 0.02% Ficoll, 0.02% BSA, and 500 mg/ml denatured salmon sperm DNA at 65° C., followed by one or more washes in 0.2×SSC, 0.01% BSA at 50° C. An isolated nucleic acid molecule of the invention that hybridizes under stringent conditions to the sequences SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, corresponds to a naturally-occurring nucleic acid molecule. As used herein, a “naturally-occurring” nucleic acid molecule refers to an RNA or DNA molecule having a nucleotide sequence that occurs in nature (e.g., encodes a natural protein).

In a second embodiment, a nucleic acid sequence that is hybridizable to the nucleic acid molecule comprising the nucleotide sequence of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, or fragments, analogs or derivatives thereof, under conditions of moderate stringency is provided. A non-limiting example of moderate stringency hybridization conditions are hybridization in 6×SSC, 5× Denhardt's solution, 0.5% SDS and 100 mg/ml denatured salmon sperm DNA at 55° C., followed by one or more washes in 1×SSC, 0.1% SDS at 37° C. Other conditions of moderate stringency that may be used are well-known within the art. See, e.g., Ausubel, et al. (eds.), 1993, CURRENT PROTOCOLS IN MOLECULAR BIOLOGY, John Wiley & Sons, NY, and Kriegler, 1990; GENE TRANSFER AND EXPRESSION, A LABORATORY MANUAL, Stockton Press, NY.

In a third embodiment, a nucleic acid that is hybridizable to the nucleic acid molecule comprising the nucleotide sequences SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, or fragments, analogs or derivatives thereof, under conditions of low stringency, is provided. A non-limiting example of low stringency hybridization conditions are hybridization in 35% formamide, 5×SSC, 50 mM Tris-HCl (pH 7.5), 5 mM EDTA, 0.02% PVP, 0.02% Ficoll, 0.2% BSA, 100 mg/ml denatured salmon sperm DNA, 10% (wt/vol) dextran sulfate at 40° C., followed by one or more washes in 2×SSC, 25 mM Tris-HCl (pH 7.4), 5 mM EDTA, and 0.1%/o SDS at 50° C. Other conditions of low stringency that may be used are well known in the art (e.g., as employed for cross-species hybridizations). See, e.g., Ausubel, et al. (eds.), 1993, . CURRENT PROTOCOLS IN MOLECULAR BIOLOGY, John Wiley & Sons, NY, and Kriegler, 1990, GENE TRANSFER AND EXPRESSION, A LABORATORY MANUAL, Stockton Press, NY; Shilo and Weinberg, 1981. Proc Natl Acad Sci USA 78: 6789-6792.

Conservative Mutations

In addition to naturally-occurring allelic variants of SECX and/or NOVX sequences that may exist in the population., the skilled artisan will further appreciate that changes can be introduced by mutation into the nucleotide sequences SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, thereby leading to changes in the amino acid sequences of the encoded SECX and/or NOVX proteins, without altering the functional ability of said SECX and/or NOVX proteins. For example, nucleotide substitutions leading to amino acid substitutions at “non-essential” amino acid residues can be made in the sequence SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40. A “non-essential” amino acid residue is a residue that can be altered from the wild-type sequences of the SECX and/or NOVX proteins without altering their biological activity, whereas an “essential” amino acid residue is required for such biological activity. For example, amino acid residues that are conserved among the SECX and/or NOVX proteins of the invention are predicted to be particularly non-amenable to alteration. Amino acids for which conservative substitutions can be made are well-known within the art.

Another aspect of the invention pertains to nucleic acid molecules encoding SECX and/or NOVX proteins that contain changes in amino acid residues that are not essential for activity. Such SECX and/or NOVX proteins differ in amino acid sequence from SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39 yet retain biological activity. In one embodiment, the isolated nucleic acid molecule comprises a nucleotide sequence encoding a protein, wherein the protein comprises an amino acid sequence at least about 45% homologous to the amino acid sequences SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 and 40. Preferably, the protein encoded by the nucleic acid molecule is at least about 60% homologous to SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 and 40; more preferably at least about 70% homologous SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40; still more preferably at least about 80% homologous to SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40; even more preferably at least about 90% homologous to SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40; and most preferably at least about 95% homologous to SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40.

An isolated nucleic acid molecule encoding an SECX and/or NOVX protein homologous to the protein of SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40 can be created by introducing one or more nucleotide substitutions, additions or deletions into the nucleotide sequence of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, such that one or more amino acid substitutions, additions or deletions are introduced into the encoded protein.

Mutations can be introduced into SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39 by standard techniques, such as site-directed mutagenesis and PCR-mediated mutagenesis. Preferably, conservative amino acid substitutions are made at one or more predicted, non-essential amino acid residues. A “conservative amino acid substitution” is one in which the amino acid residue is replaced with an amino acid residue having a similar side chain. Families of amino acid residues having similar side chains have been defined within the art. These families include amino acids with basic side chains (e.g., lysine, arginine, histidine), acidic side chains (e.g., aspartic acid, glutamic acid), uncharged polar side chains (e.g., glycine, asparagine, glutamine, serine, threonine, tyrosine, cysteine), nonpolar side chains (e.g., alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, tryptophan), beta-branched side chains (e.g., threonine, valine, isoleucine) and aromatic side chains (e.g., tyrosine, phenylalanine, tryptophan, histidine). Thus, a predicted non-essential amino acid residue in the SECX and/or NOVX protein is replaced with another amino acid residue from the same side chain family. Alternatively, in another embodiment, mutations can be introduced randomly along all or part of an SECX and/or NOVX coding sequence, such as by saturation mutagenesis, and the resultant mutants can be screened for SECX and/or NOVX biological activity to identify mutants that retain activity. Following mutagenes is SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, the encoded protein can be expressed by any recombinant technology known in the art and the activity of the protein can be determined.

The relatedness of amino acid families may also be determined based on side chain interactions. Substituted amino acids may be fully conserved “strong” residues or fully conserved “weak” residues. The “strong” group of conserved amino acid residues may be any one of the following groups: STA, NEQK, NHQK, NDEQ, QHRK, MILV, MILF, HY, FYW, wherein the single letter amino acid codes are grouped by those amino acids that may be substituted for each other. Likewise, the “weak” group of conserved residues may be any one of the following: CSA, ATV, SAPG, STNK, STPA, SGND, SNDEQK, NDEQHK, NEQHRK, VLIM, HFY, wherein the letters within each group represent the single letter amino acid code.

In one embodiment, a mutant SECX and/or NOVX protein can be assayed for (i) the ability to form protein:protein interactions with other SECX and/or NOVX proteins, other cell-surface proteins, or biologically-active portions thereof, (ii) complex formation between a mutant SECX and/or NOVX protein and an SECX and/or NOVX ligand; or (iii) the ability of a mutant SECX and/or NOVX protein to bind to an intracellular target protein or biologically-active portion thereof, (e.g. avidin proteins).

In yet another embodiment, a mutant SECX and/or NOVX protein can be assayed for the ability to regulate a specific biological function (e.g., regulation of insulin release).

Antisense Nucleic Acids

Another aspect of the invention pertains to isolated antisense nucleic acid molecules that are hybridizable to or complementary to the nucleic acid molecule comprising the nucleotide sequence of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, or fragments, analogs or derivatives thereof. An “antisense” nucleic acid comprises a nucleotide sequence that is complementary to a “sense” nucleic acid encoding a protein (e.g., complementary to the coding strand of a double-stranded cDNA molecule or complementary to an mRNA sequence). In specific aspects, antisense nucleic acid molecules are provided that comprise a sequence complementary to at least about 10, 25, 50, 100, 250 or 500 nucleotides or an entire SECX and/or NOVX coding strand, or to only a portion thereof. Nucleic acid molecules encoding fragments, homologs, derivatives and analogs of an SECX and/or NOVX protein of SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40, or antisense nucleic acids complementary to an SECX and/or NOVX nucleic acid sequence of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, are additionally provided.

In one embodiment, an antisense nucleic acid molecule is antisense to a “coding region” of the coding strand of a nucleotide sequence encoding an SECX and/or NOVX protein. The term “coding region” refers to the region of the nucleotide sequence comprising codons which are translated into amino acid residues. In another embodiment, the antisense nucleic acid molecule is antisense to a “noncoding region” of the coding strand of a nucleotide sequence encoding the SECX and/or NOVX protein. The term “noncoding region” refers to 5′ and 3′ sequences which flank the coding region that are not translated into amino acids (i.e., also referred to as 5′ and 3′ untranslated regions).

Given the coding strand sequences encoding the SECX and/or NOVX protein disclosed herein, antisense nucleic acids of the invention can be designed according to the rules of Watson and Crick or Hoogsteen base pairing. The antisense nucleic acid molecule can be complementary to the entire coding region of SECX and/or NOVX mRNA. but more preferably is an oligonucleotide that is antisense to only a portion of the coding or noncoding region of SECX and/or NOVX mRNA. For example, the antisense oligonucleotide can be complementary to the region surrounding the translation start site of SECX and/or NOVX mRNA. An antisense oligonucleotide can be, for example, about 5, 10, 15, 20, 25, 30, 35, 40, 45 or 50 nucleotides in length. An antisense nucleic acid of the invention can be constructed using chemical synthesis or enzymatic ligation reactions using procedures known in the art. For example, an antisense nucleic acid (e.g., an antisense oligonucleotide) can be chemically synthesized using naturally-occurring nucleotides or variously modified nucleotides designed to increase the biological stability of the molecules or to increase the physical stability of the duplex formed between the antisense and sense nucleic acids (e.g., phosphorothioate derivatives and acridine substituted nucleotides can be used).

Examples of modified nucleotides that can be used to generate the antisense nucleic acid include:5-fluorouracil, 5-bromouracil, 5-chlorouracil, 5-iodouracil, hypoxanthine, xanthine, 4-acetylcytosine, 5-(carboxyhydroxylmethyl) uracil, 5-carboxymethylaminomethyl-2-thiouridine, 5-carboxymethylaminomethyluracil, dihydrouracil, beta-D-galactosylqueosine, inosine, N6-isopentenyladenine, 1-methylguanine, 1-methylinosine, 2,2-dimethylguanine, 2-methyladenine, 2-methylguanine, 3-methylcytosine, 5-methylcytosine, N6-adenine, 7-methylguanine, 5-methylaminomethyluracil, 5-methoxyaminomethyl-2-thiouracil, beta-D-mannosylqueosine, 5′-methoxycarboxymethyluracil, 5-methoxyuracil, 2-methylthio-N6-isopentenyladenine, uracil-5-oxyacetic acid (v), wybutoxosine, pseudouracil, queosine, 2-thiocytosine, 5-methyl-2-thiouracil, 2-thiouracil, 4-thiouracil, 5-methyluracil, uracil-5-oxyacetic acid methylester, uracil-5-oxyacetic acid (v), 5-methyl-2-thiouracil, 3-(3-amino-3-N-2-carboxypropyl) uracil, (acp3)w, and 2,6-diaminopurine. Alternatively, the antisense nucleic acid can be produced biologically using an expression vector into which a nucleic acid has been subcloned in an antisense orientation (i.e., RNA transcribed from the inserted nucleic acid will be of an antisense orientation to a target nucleic acid of interest, described further in the following subsection).

The antisense nucleic acid molecules of the invention are typically administered to a subject or generated in situ such that they hybridize with or bind to cellular mRNA and/or genomic DNA encoding an SECX and/or NOVX protein to thereby inhibit expression of the protein (e.g, by inhibiting transcription and/or translation). The hybridization can be by conventional nucleotide complementarity to form a stable duplex, or, for example, in the case of an antisense nucleic acid molecule that binds to DNA duplexes, through specific interactions in the major groove of the double helix. An example of a route of administration of antisense nucleic acid molecules of the invention includes direct injection at a tissue site. Alternatively, antisense nucleic acid molecules can be modified to target selected cells and then administered systemically. For example, for systemic administration, antisense molecules can be modified such that they specifically bind to receptors or antigens expressed on a selected cell surface (eg., by linking the antisense nucleic acid molecules to peptides or antibodies that bind to cell surface receptors or antigens). The antisense nucleic acid molecules can also be delivered to cells using the vectors described herein. To achieve sufficient nucleic acid molecules, vector constructs in which the antisense nucleic acid molecule is placed under the control of a strong pol II or pol III promoter are preferred.

In yet another embodiment, the antisense nucleic acid molecule of the invention is an α-anomeric nucleic acid molecule. An α-anomeric nucleic acid molecule forms specific double-stranded hybrids with complementary RNA in which, contrary to the usual β-units, the strands run parallel to each other. See, e.g., Gaultier, et al., 1987. Nucl. Acids Res. 15: 6625-6641. The antisense nucleic acid molecule can also comprise a 2′-o-methylribonucleotide (See, e.g., Inoue, et al. 1987. Nucl. Acids Res. 15: 6131-6148) or a chimeric RNA-DNA analogue (See, e.g., Inoue, et al., 1987. FEBS Lett. 215: 327-330.

Ribozymes and PNA Moieties

Nucleic acid modifications include, by way of non-limiting example, modified bases, and nucleic acids whose sugar phosphate backbones are modified or derivatized. These modifications are carried out at least in part to enhance the chemical stability of the modified nucleic acid, such that they may be used, for example, as antisense binding nucleic acids in therapeutic applications in a subject.

In one embodiment, an antisense nucleic acid of the invention is a ribozyme. Ribozymes are catalytic RNA molecules with ribonuclease activity that are capable of cleaving a single-stranded nucleic acid, such as an mRNA, to which they have a complementary region. Thus, ribozymes (e.g., hammerhead ribozymes as described in Haselhoff and Gerlach 1988. Nature 334: 585-591) can be used to catalytically cleave SECX and/or NOVX mRNA transcripts to thereby inhibit translation of SECX and/or NOVX mRNA. A ribozyme having specificity for an SECX and/or NOVX-encoding nucleic acid can be designed based upon the nucleotide sequence of an SECX and/or NOVX cDNA disclosed herein (i.e.,SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39). For example, a derivative of a Tetrahymena L-19 IVS RNA can be constructed in which the nucleotide sequence of the active site is complementary to the nucleotide sequence to be cleaved in an SECX and/or NOVX-encoding mRNA. See, e g., U.S. Pat. No. 4,987,071 to Cech, et al. and U.S. Pat. No. 5,116,742 to Cech, et al. SECX and/or NOVX mRNA can also be used to select a catalytic RNA having a specific ribonuclease activity from a pool of RNA molecules. See, e.g., Bartel et al., (1993) Science 261:1411 -1418.

Alternatively, SECX and/or NOVX gene expression can be inhibited by targeting nucleotide sequences complementary to the regulatory region of the SECX and/or NOVX nucleic acid (e.g., the SECX and/or NOVX promoter and/or enhancers) to form triple helical structures that prevent transcription of the SECX and/or NOVX gene in target cells. See, e.g., Helene, 1991. Anticancer Drug Des. 6: 569-84; Helene, et al. 1992. Ann. N. Y Acad. Sci. 660: 27-36; Maher, 1992. Bioassays 14: 807-15.

In various embodiments, the SECX and/or NOVX nucleic acids can be modified at the base moiety, sugar moiety or phosphate backbone to improve, e.g., the stability, hybridization, or solubility of the molecule. For example, the deoxyribose phosphate backbone of the nucleic acids can be modified to generate peptide nucleic acids. See, e.g., Hyrup, et al., 1996. Bioorg Med Chem 4: 5-23. As used herein, the terms “peptide nucleic acids” or “PNAs” refer to nucleic acid mimics (e.g., DNA mimics) in which the deoxyribose phosphate backbone is replaced by a pseudopeptide backbone and only the four natural nucleobases are retained. The neutral backbone of PNAs has been shown to allow for specific hybridization to DNA and RNA under conditions of low ionic strength. The synthesis of PNA oligomers can be performed using standard solid phase peptide synthesis protocols as described in Hyrup, et al., 1996. supra; Perry-O'Keefe, et al., 1996. Proc. Natl Acad Sci. USA 93: 14670-14675.

PNAs of SECX and/or NOVX can be used in therapeutic and diagnostic applications. For example, PNAs can be used as antisense or antigene agents for sequence-specific modulation of gene expression by, e.g., inducing transcription or translation arrest or inhibiting replication. PNAs of SECX and/or NOVX can also be used, for example, in the analysis of single base pair mutations in a gene (e.g., PNA directed PCR clamping; as artificial restriction enzymes when used in combination with other enzymes, e.g., S₁ nucleases (See, Hyrup, et al., 1996, supra); or as probes or primers for DNA sequence and hybridization (See, Hyrup, et al., 1996, supra; Perry-O'Keefe, et al., 1996. supra)

In another embodiment, PNAs of SECX and/or NOVX can be modified, e.g., to enhance their stability or cellular uptake, by attaching lipophilic or other helper groups to PNA, by the formation of PNA-DNA chimeras, or by the use of liposomes or other techniques of drug delivery known in the art. For example, PNA-DNA chimeras of SECX and/or NOVX can be generated that may combine the advantageous properties of PNA and DNA. Such chimeras allow DNA recognition enzymes (e.g, RNase H and DNA polymerases) to interact with the DNA portion while the PNA portion would provide high binding affinity and specificity. PNA-DNA chimeras can be linked using linkers of appropriate lengths selected in terms of base stacking, number of bonds between the nucleobases, and orientation (see, Hyrup, et al., 1996. supra). The synthesis of PNA-DNA chimeras can be performed as described in Hyrup, et al., 1996. supra and Finn, et al., 1996. Nucl Acid Res 24: 3357-3363. For example, a DNA chain can be synthesized on a solid support using standard phosphoramidite coupling chemistry, and modified nucleoside analogs, e.g., 5′-(4-methoxytrityl)amino-5′-deoxy-thymidine phosphoramidite, can be used between the PNA and the 5′ end of DNA. See, e.g., Mag, et al., 1989. Nucl Acid Res 17: 5973-5988. PNA monomers are then coupled in a stepwise manner to produce a chimeric molecule with a 5′ PNA segment and a 3′ DNA segment. See, e.g., Finn, et al., 1996. supra. Alternatively, chimeric molecules can be synthesized with a 5′ DNA segment and a 3′ PNA segment. See, e.g., Petersen, et al., 1975. Bioorg. Med. Chem. Lett. 5: 1119-11124.

In other embodiments, the oligonucleotide may include other appended groups such as peptides (e.g., for targeting host cell receptors in vivo), or agents facilitating transport across the cell membrane (see, e.g., Letsinger, et al., 1989. Proc. Natl. Acad. Sci. U.S.A. 86: 6553-6556; Lemaitre, et al., 1987. Proc. Natl. Acad. Sci. 84: 648-652; PCT Publication No. WO88/09810) or the blood-brain barrier (see, e.g., PCT Publication No. WO 89/10134). In addition, oligonucleotides can be modified with hybridization triggered cleavage agents (see, e.g., Krol, et al., 1988. BioTechniques 6:958-976) or intercalating agents (see, e.g., Zon, 1988. Pharm. Res. 5: 539-549). To this end, the oligonucleotide may be conjugated to another molecule, e.g., a peptide, a hybridization triggered cross-linking agent, a transport agent, a hybridization-triggered cleavage agent, and the like.

SECX and/or NOVX Polypeptides

A polypeptide according to the invention includes a polypeptide including the amino acid sequence of SECX and/or NOVX polypeptides whose sequences are provided in SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 13, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40. The invention also includes a mutant or variant protein any of whose residues may be changed from the corresponding residues shown in SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40 while still encoding a protein that maintains its SECX and/or NOVX activities and physiological functions, or a functional fragment thereof.

In general, an SECX and/or NOVX variant that preserves SECX and/or NOVX-like function includes any variant in which residues at a particular position in the sequence have been substituted by other amino acids, and further include the possibility of inserting an additional residue or residues between two residues of the parent protein as well as the possibility of deleting one or more residues from the parent sequence. Any amino acid substitution, insertion, or deletion is encompassed by the invention. In favorable circumstances, the substitution is a conservative substitution as defined above.

One aspect of the invention pertains to isolated SECX and/or NOVX proteins, and biologically-active portions thereof, or derivatives, fragments, analogs or homologs thereof. Also provided are polypeptide fragments suitable for use as immunogens to raise anti-SECX and/or NOVX antibodies. In one embodiment, native SECX and/or NOVX proteins can be isolated from cells or tissue sources by an appropriate purification scheme using standard protein purification techniques. In another embodiment, SECX and/or NOVX proteins are produced by recombinant DNA techniques. Alternative to recombinant expression, an SECX and/or NOVX protein or polypeptide can be synthesized chemically using standard peptide synthesis techniques.

An “isolated” or “purified” polypeptide or protein or biologically-active portion thereof is substantially free of cellular material or other contaminating proteins from the cell or tissue source from which the SECX and/or NOVX protein is derived, or substantially free from chemical precursors or other chemnicals when chemically synthesized. The language “substantially free of cellular material” includes preparations of SECX and/or NOVX proteins in which the protein is separated from cellular components of the cells from which it is isolated or recombinantly-produced. In one embodiment, the language “substantially free of cellular material” includes preparations of SECX and/or NOVX proteins having less than about 30% (by dry weight) of non-SECX and/or NOVX proteins (also referred to herein as a “contaminating protein”), more preferably less than about 20% of non-SECX and/or NOVX proteins, still more preferably less than about 10% of non-SECX and/or NOVX proteins, and most preferably less than about 5% of non-SECX and/or NOVX proteins. When the SECX and/or NOVX protein or biologically-active portion thereof is recombinantly-produced, it is also preferably substantially free of culture medium, i.e., culture medium represents less than about 20%, more preferably less than about 10%, and most preferably less than about 5% of the volume of the SECX and/or NOVX protein preparation.

The language “substantially free of chemical precursors or other chemicals” includes preparations of SECX and/or NOVX proteins in which the protein is separated from chemical precursors or other chemicals that are involved in the synthesis of the protein. In one embodiment, the language “substantially free of chemical precursors or other chemicals” includes preparations of SECX and/or NOVX proteins having less than about 30% (by dry weight) of chemical precursors or non-SECX and/or NOVX chemicals, more preferably less than about 20% chemical precursors or non-SECX and/or NOVX chemicals, still more preferably less than about 10% chemical precursors or non-SECX and/or NOVX chemicals, and most preferably less than about 5% chemical precursors or non-SECX and/or NOVX chemicals.

Biologically-active portions of SECX and/or NOVX proteins include peptides comprising amino acid sequences sufficiently homologous to or derived from the amino acid sequences of the SECX and/or NOVX proteins (e.g., the amino acid sequence shown in SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40) that include fewer amino acids than the full-length SECX and/or NOVX proteins, and exhibit at least one activity of an SECX and/or NOVX protein. Typically, biologically-active portions comprise a domain or motif with at least one activity of the SECX and/or NOVX protein. A biologically-active portion of an SECX and/or NOVX protein can be a polypeptide which is, for example, 10, 25, 50, 100 or more amino acid residues in length.

Moreover, other biologically-active portions, in which other regions of the protein are deleted, can be prepared by recombinant techniques and evaluated for one or more of the functional activities of a native SECX and/or NOVX protein.

In an embodiment, the SECX and/or NOVX protein has an amino acid sequence shown SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40. In other embodiments, the SECX and/or NOVX protein is substantially homologous to SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40, and retains the functional activity of the protein of SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40, yet differs in amino acid sequence due to natural allelic variation or mutagenesis, as described in detail, below. Accordingly, in another embodiment, the SECX and/or NOVX protein is a protein that comprises an amino acid sequence at least about 45% homologous to the amino acid sequence SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40, and retains the functional activity of the SECX and/or NOVX proteins of SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40.

Determining Homology Between Two or More Sequences

To determine the percent homology of two amino acid sequences or of two nucleic acids, the sequences are aligned for optimal comparison purposes (e g, gaps can be introduced in the sequence of a first amino acid or nucleic acid sequence for optimal alignment with a second amino or nucleic acid sequence). The amino acid residues or nucleotides at corresponding amino acid positions or nucleotide positions are then compared. When a position in the first sequence is occupied by the same amino acid residue or nucleotide as the corresponding position in the second sequence, then the molecules are homologous at that position (i.e., as used herein amino acid or nucleic acid “homology” is equivalent to amino acid or nucleic acid “identity”).

The nucleic acid sequence homology may be determined as the degree of identity between two sequences. The homology may be determined using computer programs known in the art, such as GAP software provided in the GCG program package. See, Needleman and Wunsch, 1970. J Mol Biol 48: 443-453. Using GCG GAP software with the following settings for nucleic acid sequence comparison: GAP creation penalty of 5.0 and GAP extension penalty of 0.3, the coding region of the analogous nucleic acid sequences referred to above exhibits a degree of identity preferably of at least 70%, 75%, 80%, 85%, 90%, 95%, 98%, or 99%, with the CDS (encoding) part of the DNA sequence shown in SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39.

The term “sequence identity” refers to the degree to which two polynucleotide or polypeptide sequences are identical on a residue-by-residue basis over a particular region of comparison. The term “percentage of sequence identity” is calculated by comparing two optimally aligned sequences over that region of comparison, determining the number of positions at which the identical nucleic acid base (e.g., A, T, C, G, U, or 1, in the case of nucleic acids) occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the region of comparison (i.e., the window size), and multiplying the result by 100 to yield the percentage of sequence identity. The term “substantial identity” as used herein denotes a characteristic of a polynucleotide sequence, wherein the polynucleotide comprises a sequence that has at least 80 percent sequence identity, preferably at least 85 percent identity and often 90 to 95 percent sequence identity, more usually at least 99 percent sequence identity as compared to a reference sequence over a comparison region.

Chimeric and Fusion Proteins

The invention also provides SECX and/or NOVX chimeric or fusion proteins. As used herein, an SECX and/or NOVX “chimeric protein” or “fusion protein” comprises an SECX and/or NOVX polypeptide operatively-linked to a non-SECX and/or NOVX polypeptide. An “SECX and/or NOVX polypeptide” refers to a polypeptide having an amino acid sequence corresponding to an SECX and/or NOVX protein SEQ ID NOS:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 or 40, whereas a “non-SECX and/or NOVX polypeptide” refers to a polypeptide having an amino acid sequence corresponding to a protein that is not substantially homologous to the SECX and/or NOVX protein, e.g., a protein that is different from the SECX and/or NOVX protein and that is derived from the same or a different organism. Within an SECX and/or NOVX fusion protein the SECX and/or NOVX polypeptide can correspond to all or a portion of an SECX and/or NOVX protein. In one embodiment, an SECX and/or NOVX fusion protein comprises at least one biologically-active portion of an SECX and/or NOVX protein. In another embodiment, an SECX and/or NOVX fusion protein comprises at least two biologically-active portions of an SECX and/or NOVX protein. In yet another embodiment, an SECX and/or NOVX fusion protein comprises at least three biologically-active portions of an SECX and/or NOVX protein. Within the fusion protein, the term “operatively-linked” is intended to indicate that the SECX and/or NOVX polypeptide and the non-SECX and/or NOVX polypeptide are fused in-frame with one another. The non-SECX and/or NOVX polypeptide can be fused to the N-terminus or C-terminus of the SECX and/or NOVX polypeptide.

In one embodiment, the fusion protein is a GST-SECX and/or NOVX fusion protein in which the SECX and/or NOVX sequences are fused to the C-terminus of the GST (glutathione S-transferase) sequences. Such fusion proteins can facilitate the purification of recombinant SECX and/or NOVX polypeptides.

In another embodiment, the fusion protein is an SECX and/or NOVX protein containing a heterologous signal sequence at its N-terminus. In certain host cells (e.g., mammalian host cells), expression and/or secretion of SECX and/or NOVX can be increased through use of a heterologous signal sequence.

In yet another embodiment, the fusion protein is an SECX and/or NOVX-immunoglobulin fusion protein in which the SECX and/or NOVX sequences are fused to sequences derived from a member of the immunoglobulin protein family. The SECX and/or NOVX-immunoglobulin fusion proteins of the invention can be incorporated into pharmaceutical compositions and administered to a subject to inhibit an interaction between an SECX and/or NOVX ligand and an SECX and/or NOVX protein on the surface of a cell, to thereby suppress SECX and/or NOVX-mediated signal transduction in vivo. The SECX and/or NOVX-immunoglobulin fusion proteins can be used to affect the bioavailability of an SECX and/or NOVX cognate ligand. Inhibition of the SECX and/or NOVX ligand/SECX and/or NOVX interaction may be useful therapeutically for both the treatment of proliferative and differentiative disorders, as well as modulating (e.g. promoting or inhibiting) cell survival. Moreover, the SECX and/or NOVX-immunoglobulin fusion proteins of the invention can be used as immunogens to produce anti-SECX and/or NOVX antibodies in a subject, to purify SECX and/or NOVX ligands, and in screening assays to identify molecules that inhibit the interaction of SECX and/or NOVX with an SECX and/or NOVX ligand.

An SECX and/or NOVX chimeric or fusion protein of the invention can be produced by standard recombinant DNA techniques. For example, DNA fragments coding for the different polypeptide sequences are ligated together in-frame in accordance with conventional techniques, e.g., by employing blunt-ended or stagger-ended termini for ligation, restriction enzyme digestion to provide for appropriate termini, filling-in of cohesive ends as appropriate, alkaline phosphatase treatment to avoid undesirable joining, and enzymatic ligation. In another embodiment, the fusion gene can be synthesized by conventional techniques including automated DNA synthesizers. Alternatively, PCR amplification of gene fragments can be carried out using anchor primers that give rise to complementary overhangs between two consecutive gene fragments that can subsequently be annealed and reamplified to generate a chimeric gene sequence (see, e.g., Ausubel, et al. (eds.) CURRENT PROTOCOLS IN MOLECULAR BIOLOGY, John Wiley & Sons, 1992). Moreover, many expression vectors are commercially available that already encode a fusion moiety (erg., a GST polypeptide). An SECX and/or NOVX-encoding nucleic acid can be cloned into such an expression vector such that the fusion moiety is linked in-frame to the SECX and/or NOVX protein.

SECX and/or NOVX Agonists and Antagonists

The invention also pertains to variants of the SECX and/or NOVX proteins that function as either SECX and/or NOVX agonists (i.e., mimetics) or as SECX and/or NOVX antagonists. Variants of the SECX and/or NOVX protein can be generated by mutagenesis (e.g., discrete point mutation or truncation of the SECX and/or NOVX protein). An agonist of the SECX and/or NOVX protein can retain substantially the same, or a subset of, the biological activities of the naturally occurring form of the SECX and/or NOVX protein. An antagonist of the SECX and/or NOVX protein can inhibit one or more of the activities of the naturally occurring form of the SECX and/or NOVX protein by, for example, competitively binding to a downstream or upstream member of a cellular signaling cascade which includes the SECX and/or NOVX protein. Thus, specific biological effects can be elicited by treatment with a variant of limited function. In one embodiment, treatment of a subject with a variant having a subset of the biological activities of the naturally occurring form of the protein has fewer side effects in a subject relative to treatment with the naturally occurring form of the SECX and/or NOVX proteins.

Variants of the SECX and/or NOVX proteins that function as either SECX and/or NOVX agonists (i.e., mimetics) or as SECX and/or NOVX antagonists can be identified by screening combinatorial libraries of mutants (e.g., truncation mutants) of the SECX and/or NOVX proteins for SECX and/or NOVX protein agonist or antagonist activity. In one embodiment, a variegated library of SECX and/or NOVX variants is generated by combinatorial mutagenesis at the nucleic acid level and is encoded by a variegated gene library. A variegated library of SECX and/or NOVX variants can be produced by, for example, enzymatically ligating a mixture of synthetic oligonucleotides into gene sequences such that a degenerate set of potential SECX and/or NOVX sequences is expressible as individual polypeptides, or alternatively, as a set of larger fusion proteins (e.g., for phage display) containing the set of SECX and/or NOVX sequences therein. There are a variety of methods which can be used to produce libraries of potential SECX and/or NOVX variants from a degenerate oligonucleotide sequence. Chemical synthesis of a degenerate gene sequence can be performed in an automatic DNA synthesizer, and the synthetic gene then ligated into an appropriate expression vector. Use of a degenerate set of genes allows for the provision, in one mixture, of all of the sequences encoding the desired set of potential SECX and/or NOVX sequences. Methods for synthesizing degenerate oligonucleotides are well-known within the art. See, e.g., Narang, 1983. Tetrahedron 39: 3; Itakura, et al., 1984. Annu. Rev. Biochem. 53: 323; Itakura, et al., 1984. Science 198: 1056; Ike, et al., 1983. Nucl. Acids Res. 11:477.

Polypeptide Libraries

In addition, libraries of fragments of the SECX and/or NOVX protein coding sequences can be used to generate a variegated population of SECX and/or NOVX fragments for screening and subsequent selection of variants of an SECX and/or NOVX protein. In one embodiment, a library of coding sequence fragments can be generated by treating a double stranded PCR fragment of an SECX and/or NOVX coding sequence with a nuclease under conditions wherein nicking occurs only about once per molecule, denaturing the double stranded DNA, renaturing the DNA to form double-stranded DNA that can include sense/antisense pairs from different nicked products, removing single stranded portions from reformed duplexes by treatment with S₁ nuclease, and ligating the resulting fragment library into an expression vector. By this method, expression libraries can be derived which encodes N-terminal and internal fragments of various sizes of the SECX and/or NOVX proteins.

Various techniques are known in the art for screening gene products of combinatorial libraries made by point mutations or truncation, and for screening cDNA libraries for gene products having a selected property. Such techniques are adaptable for rapid screening of the gene libraries generated by the combinatorial mutagenesis of SECX and/or NOVX proteins. The most widely used techniques, which are amenable to high throughput analysis, for screening large gene libraries typically include cloning the gene library into replicable expression vectors, transforming appropriate cells with the resulting library of vectors, and expressing the combinatorial genes under conditions in which detection of a desired activity facilitates isolation of the vector encoding the gene whose product was detected. Recursive ensemble mutagenesis (REM), a new technique that enhances the frequency of functional mutants in the libraries, can be used in combination with the screening assays to identify SECX and/or NOVX variants. See, e.g., Arkin and Yourvan, 1992. Proc. Natl. Acad. Sci. USA 89: 7811-7815; Delgrave, et al., 1993. Protein Engineering 6:327-331.

SECX and/or NOVX Antibodies

The term “antibody” as used herein refers to immunoglobulin molecules and immunologically active portions of immunoglobulin (Ig) molecules, i.e., molecules that contain an antigen binding site that specifically binds (immunoreacts with) an antigen. Such antibodies include, but are not limited to, polyclonal, monoclonal, chimeric, single chain, F_(ab,) F_(ab′)and F_((ab′)2) fragments, and an F_(ab) expression library. In general, antibody molecules obtained from humans relates to any of the classes IgG, IgM, IgA, IgE and IgD, which differ from one another by the nature of the heavy chain present in the molecule. Certain classes have subclasses as well, such as IgG₁, IgG₂, and others. Furthermore, in humans, the light chain may be a kappa chain or a lambda chain. Reference herein to antibodies includes a reference to all such classes, subclasses and types of human antibody species.

An isolated protein of the invention intended to serve as an antigen, or a portion or fragment thereof, can be used as an immunogen to generate antibodies that immunospecifically bind the antigen, using standard techniques for polyclonal and monoclonal antibody preparation. The full-length protein can be used or, alternatively, the invention provides antigenic peptide fragments of the antigen for use as immunogens. An antigenic peptide fragment comprises at least 6 amino acid residues of the amino acid sequence of the full length protein, such as an amino acid sequence shown in SEQ ID NOs:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 and 40, and encompasses an epitope thereof such that an antibody raised against the peptide forms a specific immune complex with the full length protein or with any fragment that contains the epitope. Preferably, the antigenic peptide comprises at least 10 amino acid residues, or at least 15 amino acid residues, or at least 20 amino acid residues, or at least 30 amino acid residues. Preferred epitopes encompassed by the antigenic peptide are regions of the protein that are located on its surface; commonly these are hydrophilic regions.

In certain embodiments of the invention, at least one epitope encompassed by the antigenic peptide is a region of SECX and/or NOVX that is located on the surface of the protein, e.g., a hydrophilic region. A hydrophobicity analysis of the human SECX and/or NOVX protein sequence will indicate which regions of a SECX and/or NOVX polypeptide are particularly hydrophilic and, therefore, are likely to encode surface residues useful for targeting antibody production. As a means for targeting antibody production, hydropathy plots showing regions of hydrophilicity and hydrophobicity may be generated by any method well known in the art, including, for example, the Kyte Doolittle or the Hopp Woods methods, either with or without Fourier transformation. See, e.g., Hopp and Woods, 1981, Proc. Nat. Acad. Sci. USA 78: 3824-3828; Kyte and Doolittle 1982, J. Mol. Biol. 157: 105-142, each incorporated herein by reference in their entirety. Antibodies that are specific for one or more domains within an antigenic protein, or derivatives, fragments, analogs or homologs thereof, are also provided herein.

A protein of the invention, or a derivative, fragment, analog, homolog or ortholog thereof, may be utilized as an immunogen in the generation of antibodies that immunospecifically bind these protein components.

Various procedures known within the art may be used for the production of polyclonal or monoclonal antibodies directed against a protein of the invention, or against derivatives, fragments, analogs homologs or orthologs thereof (see, for example, Antibodies: A Laboratory Manual, Harlow E, and Lane D, 1988, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., incorporated herein by reference). Some of these antibodies are discussed below.

Polyclonal Antibodies

For the production of polyclonal antibodies, various suitable host animals (e.g., rabbit, goat, mouse or other mammal) may be immunized by one or more injections with the native protein, a synthetic variant thereof, or a derivative of the foregoing. Am appropriate immunogenic preparation can contain, for example, the naturally occurring immunogenic protein, a chemically synthesized polypeptide representing the immunogenic protein, or a recombinantly expressed immunogenic protein. Furthermore, the protein may be conjugated to a second protein known to be immunogenic in the mammal being immunized. Examples of such immunogenic proteins include but are not limited to keyhole limpet hemocyanin, serum albumin, bovine thyroglobulin, and soybean trypsin inhibitor. The preparation can further include an adjuvant. Various adjuvants used to increase the immunological response include, but are not limited to, Freund's (complete and incomplete), mineral gels (e.g., aluminum hydroxide), surface active substances (e.g., lysolecithin, pluronic polyols, polyanions, peptides, oil emulsions, dinitrophenol, etc.), adjuvants usable in humans such as Bacille Calmette-Guerin and Corynebacterium parvum, or similar immunostimulatory agents. Additional examples of adjuvants which can be employed include MPL-TDM adjuvant (monophosphoryl Lipid A, synthetic trehalose dicorynomycolate).

The polyclonal antibody molecules directed against the immunogenic protein can be isolated from the mammal (e.g., from the blood) and farther purified by well known techniques, such as affinity chromatography using protein A or protein G, which provide primarily the IgG fraction of immune serum. Subsequently, or alternatively, the specific antigen which is the target of the immunoglobulin sought, or an epitope thereof, may be immobilized on a column to purify the immune specific antibody by immunoaffmity chromatography. Purification of immunoglobulins is discussed, for example, by D. Wilkinson (The Scientist, published by The Scientist, Inc., Philadelphia Pa., Vol. 14, No. 8 (Apr. 17, 2000), pp. 25-28).

Monoclonal Antibodies

The term “monoclonal antibody” (MAb) or “monoclonal antibody composition”, as used herein, refers to a population of antibody molecules that contain only one molecular species of antibody molecule consisting of a unique light chain gene product and a unique heavy chain gene product. In particular, the complementarity determining regions (CDRs) of the monoclonal antibody are identical in all the molecules of the population. MAbs thus contain an antigen binding site capable of immunoreacting with a particular epitope of the antigen characterized by a unique binding affinity for it.

Monoclonal antibodies can be prepared using hybridoma methods, such as those described by Kohler and Milstein, Nature 256:495 (1975). In a hybridoma method, a mouse, hamster, or other appropriate host animal, is typically immunized with an immunizing agent to elicit lymphocytes that produce or are capable of producing antibodies that will specifically bind to the immunizing agent. Alternatively, the lymphocytes can be immunized in vitro.

The immunizing agent will typically include the protein antigen, a fragment thereof or a fusion protein thereof. Generally, either peripheral blood lymphocytes are used if cells of human origin are desired, or spleen cells or lymph node cells are used if non-human mammalian sources are desired. The lymphocytes are then fused with an immortalized cell line using a suitable fusing agent, such as polyethylene glycol, to form a hybridoma cell [Goding, Monoclonal Antibodies: Princiiples and Practice, Academic Press, (1986) pp. 59-103]. Immortalized cell lines are usually transformed mammalian cells, particularly myeloma cells of rodent, bovine and human origin. Usually, rat or mouse myeloma cell lines are employed. The hybridoma cells can be cultured in a suitable culture medium that preferably contains one or more substances that inhibit the growth or survival of the unfused, immortalized cells. For example, if the parental cells lack the enzyme hypoxanthine guanine phosphoribosyl transferase (HGPRT or HPRT), the culture medium for the hybridomas typically will include hypoxanthine, aminopterin, and thymidine (“HAT medium”), which substances prevent the growth ot HGPRT-deficient cells.

Preferred immortalized cell lines are those that fuse efficiently, support stable high level expression of antibody by the selected antibody-producing cells, and are sensitive to a medium such as HAT medium. More preferred immortalized cell lines are murine myeloma lines, which can be obtained, for instance, from the Salk Institute Cell Distribution Center, San Diego, Calif. and the American Type Culture Collection, Manassas, Va. Human myeloma and mouse-human heteromyeloma cell lines also have been described for the production of human monoclonal antibodies [Kozbor, J. Immunol. 133:3001 (1984); Brodeur et al., Monoclonal Antibody Production Techniques and Applications, Marcel Dekker, Inc., New York, (1987) pp. 51-63].

The culture medium in which the hybridoma cells are cultured can then be assayed for the presence of monoclonal antibodies directed against the antigen. Preferably, the binding specificity of monoclonal antibodies produced by the hybridoma cells is determined by immunoprecipitation or by an in vitro binding assay, such as radioimmunoassay (RIA) or enzyme-linked immunoabsorbent assay (ELISA). Such techniques and assays are known in the art. The binding affinity of the monoclonal antibody can, for example, be determined by the Scatchard analysis of Munson and Pollard, Anal. Biochem., 107:220 (1980). It is an objective, especially important in therapeutic applications of monoclonal antibodies, to identify antibodies having a high degree of specificity and a high binding affinity for the target antigen.

After the desired hybridoma cells are identified, the clones can be subcloned by limiting dilution procedures and grown by standard methods (Goding,1986). Suitable culture media for this purpose include, for example, Dulbecco's Modified Eagle's Medium and RPMI-1640 medium. Alternatively, the hybridoma cells can be grown in vivo as ascites in a mammal.

The monoclonal antibodies secreted by the subclones can be isolated or purified from the culture medium or ascites fluid by conventional immunoglobulin purification procedures such as, for example, protein A-Sepharose, hydroxylapatite chromatography, gel electrophoresis, dialysis, or affinity chromatography.

The monoclonal antibodies can also be made by recombinant DNA methods, such as those described in U.S. Pat. No. 4,816,567. DNA encoding the monoclonal antibodies of the invention can be readily isolated and sequenced using conventional procedures (e.g., by using oligonucleotide probes that are capable of binding specifically to genes encoding the heavy and light chains of murine antibodies). The hybridoma cells of the invention serve as a preferred source of such DNA. Once isolated, the DNA can be placed into expression vectors, which are then transfected into host cells such as simian COS cells, Chinese hamster ovary (CHO) cells, or myeloma cells that do not otherwise produce immunoglobulin protein, to obtain the synthesis of monoclonal antibodies in the recombinant host cells. The DNA also can be modified, for example, by substituting the coding sequence for human heavy and light chain constant domains in place of the homologous murine sequences (U.S. Pat. No. 4,816,567; Morrison, Nature 368, 812-13 (1994)) or by covalently joining to the immunoglobulin coding sequence all or part of the coding sequence for a non-immunoglobulin polypeptide. Such a non-immurioglobulin polypeptide can be substituted for the constant domains of an antibody of the invention, or can be substituted for the variable domains of one antigen-combining site of an antibody of the invention to create a chimeric bivalent antibody.

Humanized Antibodies

The antibodies directed against the protein antigens of the invention can further comprise humanized antibodies or human antibodies. These antibodies are suitable for administration to humans without engendering an immune response by the human against the administered immunoglobulin. Humanized forms of antibodies are chimeric immunoglobulins, immunoglobulin chains or fragments thereof (such as Fv, Fab, Fab′, F(ab′)₂ or other antigen-binding subsequences of antibodies) that are principally comprised of the sequence of a human immunoglobulin, and contain minimal sequence derived from a non-human immunoglobulin. Humanization can be performed following the method of Winter and co-workers (Jones et al., Nature, 321:522-525 (1986); Riechmann et al., Nature, 332:323-327 (1988); Verhoeyen et al., Science, 239:1534-1536 (1988)), by substituting rodent CDRs or CDR sequences for the corresponding sequences of a human antibody. (See also U.S. Pat. No. 5,225,539.) In some instances, Fv framework residues of the human immunoglobulin are replaced by corresponding non-human residues. Humanized antibodies can also comprise residues which are found neither in the recipient antibody nor in the imported CDR or framework sequences. In general, the humanized antibody will comprise substantially all of at least one, and typically two, variable domains, in which all or substantially all of the CDR regions correspond to those of a non-human immunoglobulin and all or substantially all of the framework regions are those of a human immunoglobulin consensus sequence. The humanized antibody optimally also will comprise at least a portion of an immunoglobulin constant region (Fc), typically that of a human immunoglobulin (Jones et al., 1986; Riechmann et al., 1988; and Presta, Curr. Op. Struct. Biol. 2:593-596 (1992)).

Human Antibodies

Fully human antibodies essentially relate to antibody molecules in which the entire sequence of both the light chain and the heavy chain, including the CDRs, arise from human genes. Such antibodies are termed “human antibodies”, or “fully human antibodies” herein. Human monoclonal antibodies can be prepared by the trioma technique; the human B-cell hybridoma technique (see Kozbor, et al., 1983 Immunol Today 4: 72) and the EBV hybridoma technique to produce human monoclonal antibodies (see Cole, et al., 1985 In: MONOCLONAL ANTIBODIES AND CANCER THERAPY, Alan R. Liss, Inc., pp. 77-96). Human monoclonal antibodies may be utilized in the practice of the present invention and may be produced by using human hybridomas (see Cote, et al., 1983. Proc Natl Acad Sci USA 80: 2026-2030) or by transforming human B-cells with Epstein Barr Virus in vitro (see Cole, et al., 1985 In: MONOCLONAL ANTIBODIES AND CANCER THERAPY, Alan R. Liss, Inc., pp. 77-96).

In addition, human antibodies can also be produced using additional techniques, including phage display libraries (Hoogenboom and Winter, J. Mol. Biol., 227:381 (1991); Marks et al., J. Mol. Biol. 222:581 (1991)). Similarly, human antibodies can be made by introducing human immunoglobulin loci into transgenic animals. e.g., mice in which the endogenous immunoglobulin genes have been partially or completely inactivated. Upon challenge, human antibody production is observed, which closely resembles that seen in humans in all respects, including gene rearrangement, assembly and antibody repertoire. This approach is described, for example, in U.S. Pat. Nos. 5,545,807; 5,545,806; 5,569,825; 5,625,126; 5,633,425; 5,661,016, and in Marks et al. (Bio/Technology 10, 779-783 (1992)); Lonberg et al. (Nature 368 856-859 (1994)); Morrison (Nature 368, 812-13 (1994)); Fishwild et al,(Nature Biotechnology 14, 845-51 (1996)); Neuberger (Nature Biotechnology 14, 826 (1996)); and Lonberg and Huszar (Intern. Rev. Immunol. 13 65-93 (1995)).

Human antibodies may additionally be produced using transgenic nonhuman animals which are modified so as to produce fully human antibodies rather than the animal's endogenous antibodies in response to challenge by an antigen. (See PCT publication WO94/02602). The endogenous genes encoding the heavy and light immunoglobulin chains in the nonhuman host have been incapacitated, and active loci encoding human heavy and light chain immunoglobulins are inserted into the host's genome. The human genes are incorporated, for example, using yeast artificial chromosomes containing the requisite human DNA segments. An animal which provides all the desired modifications is then obtained as progeny by crossbreeding intermediate transgenic animals containing fewer than the full complement of the modifications. The preferred embodiment of such a nonhuman animal is a mouse, and is termed the Xenomousem as disclosed in PCT publications WO 96/33735 and WO 96/34096. This animal produces B cells which secrete fully human immunoglobulins. The antibodies can be obtained directly from the animal after immunization with an immunogen of interest, as, for example, a preparation of a polyclonal antibody, or alternatively from immortalized B cells derived from the animal, such as hybridomas producing monoclonal antibodies. Additionally, the genes encoding the immunoglobulins with human variable regions can be recovered and expressed to obtain the antibodies directly, or can be further modified to obtain analogs of antibodies such as, for example, single chain Fv molecules.

An example of a method of producing a nonhuman host, exemplified as a mouse, lacking expression of an endogenous immunoglobulin heavy chain is disclosed in U.S. Pat. No. 5,939,598. It can be obtained by a method including deleting the J segment genes from at least one endogenous heavy chain locus in an embryonic stem cell to prevent rearrangement of the locus and to prevent formation of a transcript of a rearranged immunoglobulin heavy chain locus. the deletion being effected by a targeting vector containing a gene encoding a selectable marker: and producing from the embryonic stem cell a transgenic mouse whose somatic and germ cells contain the gene encoding the selectable marker.

A method for producing; an antibody of interest, such as a human antibody, is disclosed in U.S. Pat. No. 5,916,771. It includes introducing an expression vector that contains a nucleotide sequence encoding a heavy chain into one mammalian host cell in culture, introducing an expression vector containing a nucleotide sequence encoding a light chain into another mammalian host cell, and fusing the two cells to form a hybrid cell. The hybrid cell expresses an antibody containing the heavy chain and the light chain.

In a further improvement on this procedure, a method for identifying a clinically relevant epitope on an immunogen, and a correlative method for selecting an antibody that binds immunospecifically to the relevant epitope with high affinity, are disclosed in PCT publication WO 99/53049.

F_(ab) Fragments and Single Chain Antibodies

According to the invention, techniques can be adapted for the production of single-chain antibodies specific to an antigenic protein of the invention (see e.g., U.S. Pat. No. 4,946,778). In addition, methods can be adapted for the construction of F_(ab) expression libraries (see e.g., Huse, et al., 1989 Science 246: 1275-1281) to allow rapid and effective identification of monoclonal F_(ab) fragments with the desired specificity for a protein or derivatives, fragments, analogs or homologs thereof. Antibody fragments that contain the idiotypes to a protein antigen may be produced by techniques known in the art including, but not limited to: (i) an F_((ab)2) fragment produced by pepsin digestion of an antibody molecule; (ii) an F_(ab) fragment generated by reducing the disulfide bridges of an F_((ab′)2) fragment; (iii) an F_(ab) fragment generated by the treatment of the antibody molecule with papain and a reducing agent and (iv) F_(v) fragments.

Bispecific Antibodies

Bispecific antibodies are monoclonal, preferably human or humanized, antibodies that have binding specificities for at least two different antigens. In the present case, one of the binding specificities is for an antigenic protein of the invention. The second binding target is any other antigen, and advantageously is a cell-surface protein or receptor or receptor subunit.

Methods for making bispecific antibodies are known in the art. Traditionally, the recombinant production of bispecific antibodies is based on the co-expression of two immunoglobulin heavy-chain/light-chain pairs, where the two heavy chains have different specificities (Milstein and Cuello, Nature, 305:537-539 (1983)) Because of the random assortment of immunoglobulin heavy and light chains, these hybridomas (quadromas) produce a potential mixture of ten different antibody molecules, of which only one has the correct bispecific structure. The purification of the correct molecule is usually accomplished by affinity chromatography steps. Similar procedures are disclosed in WO 93/08829, published May 13, 1993, and in Traunecker et al., EMBO J., 10:3655-3659 (1991).

Antibody variable domains with the desired binding specificities (antibody-antigen combining sites) can be fused to immunoglobulin constant domain sequences. The fusion preferably is with an immunoglobulin heavy-chain constant domain, comprising at least part of the hinge, CH2, and CH3 regions. It is preferred to have the first heavy-chain constant region (CH1) containing the site necessary for light-chain binding present in at least one of the fusions. DNAs encoding the immunoglobulin heavy-chain fusions and, if desired, the immunoglobulin light chain, are inserted into separate expression vectors, and are co-transfected into a suitable host organism. For further details of generating bispecific antibodies see, for example, Suresh et al., Methods in Enzymology, 121:210 (1986).

According to another approach described in WO 96/2701 1, the interface between a pair of antibody molecules can be engineered to maximize the percentage of heterodimers which are recovered from recombinant cell culture. The preferred interface comprises at least a part of the CH3 region of an antibody constant domain. In this method, one or more small amino acid side chains from the interface of the first antibody molecule are replaced with larger side chains (e.g. tyrosine or tryptophan). Compensatory “cavities” of identical or similar size to the large side chain(s) are created on the interface of the second antibody molecule by replacing large amino acid side chains with smaller ones (e.g. alanine or threonine). This provides a mechanism for increasing the yield of the heterodimer over other unwanted end-products such as homodimers.

Bispecific antibodies can be prepared as full length antibodies or antibody fragments (e.g. F(ab′)₂ bispecific antibodies). Techniques for generating bispecific antibodies from antibody fragments have been described in the literature. For example, bispecific antibodies can be prepared using chemical linkage. Brennan et al., Science 229:81 (1985) describe a procedure wherein intact antibodies are proteolytically cleaved to generate F(ab′)₂ fragments. These fragments are reduced in the presence of the dithiol complexing agent sodium arsenite to stabilize vicinal dithiols and prevent intermolecular disulfide formation. The Fab′ fragments generated are then converted to thionitrobenzoate (TNB) derivatives. One of the Fab′-TNB derivatives is then reconverted to the Fab′-thiol by reduction with mercaptoethylamine and is mixed with an equimolar amount of the other Fab′-TNB derivative to form the bispecific antibody. The bispecific antibodies produced can be used as agents for the selective immobilization of enzymes.

Additionally, Fab′ fragments can be directly recovered from E. coli and chemically coupled to form bispecific antibodies. Shalaby et al., J. Exp. Med. 175:217-225 (1992) describe the production of a fully humanized bispecific antibody F(ab′)₂ molecule. Each Fab′ fragment was separately secreted from E. coli and subjected to directed chemical coupling in vitro to form the bispecific antibody. The bispecific antibody thus formed was able to bind to cells overexpressing the ErbB2 receptor and normal human T cells, as well as trigger the lytic activity of human cytotoxic lymphocytes against human breast tumor targets.

Various techniques for making and isolating bispecific antibody fragments directly from recombinant cell culture have also been described. For example, bispecific antibodies have been produced using leucine zippers. Kostelny et al., J. Immunol. 148(5):1547-1553 (1992). The leucine zipper peptides from the Fos and Jun proteins were linked to the Fab′ portions of two different antibodies by gene fusion. The antibody homodimers were reduced at the hinge region to form monomers and then re-oxidized to form the antibody heterodimers. This method can also be utilized for the production of antibody homodimers. The “diabody” technology described by Hollinger et al., Proc. Natl. Acad. Sci. USA 90:6444-6448 (1993) has provided an alternative mechanism for making bispecific antibody fragments. The fragments comprise a heavy-chain variable domain (V_(H)) connected to a light-chain variable domain (V_(L)) by a linker which is too short to allow pairing between the two domains on the same chain. Accordingly, the V_(H) and V_(L) domains of one fragment are forced to pair with the complementary V_(L) and V_(H) domains of another fragment, thereby forming two antigen-binding sites. Another strategy for making bispecific antibody fragments by the use of single-chain Fv (sFv) dimers has also been reported. See, Gruber et al., J. Immunol. 152:5368 (1994).

Antibodies with more than two valencies are contemplated. For example, trispecific antibodies can be prepared. Tutt et al., J. Immunol. 147:60 (1991).

Exemplary bispecific antibodies can bind to two different epitopes, at least one of which originates in the protein antigen of the invention. Alternatively, an anti-antigenic arm of an immunoglobulin molecule can be combined with an arm which binds to a triggering molecule on a leukocyte such as a T-cell receptor molecule (e.g. CD2, CD3. CD28, or B7), or Fc receptors for IgG (FcγR), such as FcγRI (CD64), FcγRII (CD32) and FcγRIII (CD16) so as to focus cellular defense mechanisms to the cell expressing the particular antigen. Bispecific antibodies can also be used to direct cytotoxic agents to cells which express a particular antigen. These antibodies possess an antigen-binding arm and an arm which binds a cytotoxic agent or a radionuclide chelator, such as EOTUBE, DPTA, DOTA, or TETA. Another bispecific antibody of interest binds the protein antigen described herein and further binds tissue factor (TF).

Heteroconjugate Antibodies

Heteroconjugate antibodies are also within the scope of the present invention. Heteroconjugate antibodies are composed of two covalently joined antibodies. Such antibodies have, for example, been proposed to target immune system cells to unwanted cells (U.S. Pat. No. 4,676,980), and for treatment of HIV infection (WO 91/00360; WO 92/200373; EP 03089). It is contemplated that the antibodies can be prepared in vitro using known methods in synthetic protein chemistry, including those involving crosslinking agents. For example, immunotoxins can The constructed using a disulfide exchange reaction or by forming a thioether bond. Examples of suitable reagents for this purpose include iminothiolate and methyl-4-mercaptobutyrimidate and those disclosed, for example, in U.S. Pat. No. 4,676,980.

Effector Function Engineering

It can be desirable to modify the antibody of the invention with respect to effector function, so as to enhance, e.g., the effectiveness of the antibody in treating cancer. For example, cysteine residue(s) can be introduced into the Fc region, thereby allowing interchain disulfide bond formation in this region. The homodimeric antibody thus generated can have improved internalization capability and/or increased complement-mediated cell killing and antibody-dependent cellular cytotoxicity (ADCC). See Caron et al., J. Exp Med., 176: 1191-1195 (1992) and Shopes, J. Immunol., 148: 2918-2922 (1992). Homodimeric antibodies with enhanced anti-tumor activity can also be prepared using heterobiflimctional cross-linkers as described in Wolff et al. Cancer Research, 53: 2560-2565 (1993). Alternatively, an antibody can be engineered that has dual Fc regions and can thereby have enhanced complement lysis and ADCC capabilities. See Stevenson et al., Anti-Cancer Drug Design 3: 219-230 (1989).

Immunoconjugates

The invention also pertains to immunoconjugates comprising an antibody conjugated to a cytotoxic agent such as a chemotherapeutic agent, toxin (e.g., an enzymatically active toxin of bacterial, fungal, plant, or animal origin or fragments thereof), or a radioactive isotope (i.e., a radioconjugate).

Chemotherapeutic agents useful in the generation of such immunoconjugates have been described above. Enzymatically active toxins and fragments thereof that can be used include diphtheria A chain, nonbinding active fragments of diphtheria toxin, exotoxin A chain (from Pseudomonas aeruginosa), ricin A chain, abrin A chain, modeccin A chain, alpha-sarcin, Aleurites fordii proteins, dianthin proteins, Phytolaca americana proteins (PAPI, PAPII, and PAP-S), momordica charantia inhibitor, curcin, crotin, sapaonaria officinalis inhibitor, gelonin, mitogellin, restrictocin, phenomycin, enomycin, and the tricothecenes. A variety of radionuclides are available for the production of radioconjugated antibodies. Examples include ²¹²Bi, ¹³¹I, ¹³¹In, ⁹⁰Y, and ¹⁸⁶Re.

Conjugates of the antibody and cytotoxic agent are made using a variety of bifunctional protein-coupling agents such as N-succinimidyl-3-(2-pyridyldithiol) propionate (SPDP), iminothiolane (IT), bifunctional derivatives of imidoesters (such as dimethyl adipimidate HCL), active esters (such as disuccinimidyl suberate), aldehydes (such as glutareldehyde), bis-azido compounds (such as bis (p-azidobenzoyl) hexanediamine), bis-diazonium derivatives (such as bis-(p-diazoniumbenzoyl)-ethylenediamine), diisocyanates (such as tolyene 2,6-diisocyanate), and bis-active fluorine compounds (such as 1,5-difluoro-2,4-dinitrobenzene). For example, a ricin immunotoxin can be prepared as described in Vitetta et al., Science, 238: 1098 (1987). Carbon-14-labeled 1-isothiocyanatobenzyl-3-methyldiethylene triaminepentaacetic acid (MX-DTPA) is an exemplary chelating agent for conjugation of radionucleotide to the antibody. See WO094/11026.

In another embodiment, the antibody can be conjugated to a “receptor” (such streptavidin) for utilization in tumor pretargeting wherein the antibody-receptor conjugate is administered to the patient, followed by removal of unbound conjugate from the circulation using a clearing agent and then administration of a “ligand” (e.g., avidin) that is in turn conjugated to a cytotoxic agent.

Immunoliposomes

The antibodies disclosed herein can also be formulated as immunoliposomes. Liposomes containing the antibody are prepared by methods known in the art, such as described in Epstein et al., Proc. Natl. Acad. Sci. USA, 82: 3688 (1985); Hwang et al., Proc. Natl Acad. Sci. USA, 77: 4030 (1980); and U.S. Pat Nos. 4,485,045 and 4,544,545. Liposomes with enhanced circulation time are disclosed in U.S. Pat. No. 5,013,556.

Particularly useful liposomes can be generated by the reverse-phase evaporation method with a lipid composition comprising phosphatidylcholine, cholesterol, and PEG-derivatized phosphatidylethanolamine (PEG-PE). Liposomes are extruded through filters of defined pore size to yield liposomes with the desired diameter. Fab′ fragments of the antibody of the present invention can be conjugated to the liposomes as described in Martin et al., J. Biol. Chem., 257: 286-288 (1982) via a disulfide-interchange reaction. A chemotherapeutic agent (such as Doxorubicin) is optionally contained within the liposome. See Gabizon et al., J. National Cancer Inst., 81(19): 1484 (1989).

Diagnostic Applications of Antibodies Directed Against the Proteins of the Invention

Antibodies directed against a protein of the invention may be used in methods known within the art relating to the localization and/or quantitation of the protein (e.g., for use in measuring levels of the protein within appropriate physiological samples, for use in diagnostic methods, for use in imaging the protein, and the like). In a given embodiment, antibodies against the proteins, or derivatives, fragments, analogs or homologs thereof, that contain the antigen binding domain, are utilized as pharmacologically-active compounds (see below).

An antibody specific for a protein of the invention can be used to isolate the protein by standard techniques, such as immunoaffinity chromatography or immunoprecipitation. Such an antibody can facilitate the purification of the natural protein antigen from cells and of recombinantly produced antigen expressed in host cells. Moreover, such an antibody can be used to detect the antigenic protein (e.g., in a cellular lysate or cell supernatant) in order to evaluate the abundance and pattern of expression of the antigenic protein. Antibodies directed against the protein can be used diagnostically to monitor protein levels in tissue as part of a clinical testing procedure, e.g., to, for example, determine the efficacy of a given treatment regimen. Detection can be facilitated by coupling (i.e., physically linking) the antibody to a detectable substance. Examples of detectable substances include various enzymes, prosthetic groups, fluorescent materials, luminescent materials, bioluminescent materials, and radioactive materials. Examples of suitable enzymes include horseradish peroxidase, alkaline phosphatase, β-galactosidase, or acetylcholinesterase; examples of suitable prosthetic group complexes include streptavidin/biotin and avidin/biotin; examples of suitable fluorescent materials include umbelliferone, fluorescein, fluorescein isothiocyanate, rhodamine, dichlorotriazinylamine fluorescein, dansyl chloride or phycoerythrin; an example of a luminescent material includes luminol; examples of bioluminescent materials include luciferase, luciferin, and aequorin, and examples of suitable radioactive material include ¹²⁵I, ¹³¹I, ³⁵S or ³H.

Antibody Therapeutics

Antibodies of the invention, including polyclonal, monoclonal, humanized and fully human antibodies, may used as therapeutic agents. Such agents will generally be employed to treat or prevent a disease or pathology in a subject. An antibody preparation, preferably one having high specificity and high affinity for its target antigen, is administered to the subject and will generally have an effect due to its binding with the target. Such an effect may be one of two kinds, depending on the specific nature of the interaction between the given antibody molecule and the target antigen in question. In the first instance, administration of the antibody may abrogate or inhibit the binding of the target with an endogenous ligand to which it naturally binds. In this case, the antibody binds to the target and masks a binding site of the naturally occurring ligand, wherein the ligand serves as an effector molecule. Thus the receptor mediates a signal transduction pathway for which ligand is responsible.

Alternatively, the effect may be one in which the antibody elicits a physiological result by virtue of binding to an effector binding site on the target molecule. In this case the target, a receptor having an endogenous ligand which may be absent or defective in the disease or pathology, binds the antibody as a surrogate effector ligand, initiating a receptor-based signal transduction event by the receptor.

A therapeutically effective amount of an antibody of the invention relates generally to the amount needed to achieve a therapeutic objective. As noted above, this may be a binding interaction between the antibody and its target antigen that, in certain cases, interferes with the functioning of the target, and in other cases, promotes a physiological response. The amount required to be administered will furthermore depend on the binding affinity of the antibody for its specific antigen, and will also depend on the rate at which an administered antibody is depleted from the free volume other subject to which it is administered. Common ranges for therapeutically effective dosing of an antibody or antibody fragment of the invention may be, by way of nonlimiting example, from about 0.1 mg/kg body weight to about 50 mg/kg body weight. Common dosing frequencies may range, for example, from twice daily to once a week.

Pharmaceutical Compositions of Antibodies

Antibodies specifically binding a protein of the invention, as well as other molecules identified by the screening assays disclosed herein, can be administered for the treatment of various disorders in the form of pharmaceutical compositions. Principles and considerations involved in preparing such compositions, as well as guidance in the choice of components are provided, for example, in Remington: The Science And Practice Of Pharmacy 19th ed. (Alfonso R. Gennaro, et al., editors) Mack Pub. Co., Easton, Pa.: 1995; Drug Absorption Enhancement: Concepts, Possibilities, Limitations, And Trends, Harwood Academic Publishers, Langhorne, Pa., 1994; and Peptide And Protein Drug Delivery (Advances In Parenteral Sciences, Vol. 4), 1991, M. Dekker, New York.

If the antigenic protein is intracellular and whole antibodies are used as inhibitors, internalizing antibodies are preferred. However, liposomes can also be used to deliver the antibody, or an antibody fragment, into cells. Where antibody fragments are used, the smallest inhibitory fragment that specifically binds to the binding domain of the target protein is preferred. For example, based upon the variable-region sequences of an antibody, peptide molecules can be designed that retain the ability to bind the target protein sequence. Such peptides can be synthesized chemically and/or produced by recombinant DNA technology. See, e.g., Marasco et al., Proc. Natl. Acad. Sci. USA, 90: 7889-7893 (1993). The formulation herein can also contain more than one active compound as necessary for the particular indication being treated, preferably those with complementary activities that do not adversely affect each other. Alternatively, or in addition, the composition can comprise an agent that enhances its function, such as, for example, a cytotoxic agent, cytokine, chemotherapeutic agent, or growth-inhibitory agent. Such molecules are suitably present in combination in amounts that are effective for the purpose intended.

The active ingredients can also be entrapped in microcapsules prepared, for example, by coacervation techniques or by interfacial polymerization, for example, hydroxymethylcellulose or gelatin-microcapsules and poly-(methylmethacrylate) microcapsules, respectively, in colloidal drug delivery systems (for example, liposomes, albumin microspheres, microemulsions, nano-particles, and nanocapsules) or in macroemulsions.

The formulations to be used for in vivo administration must be sterile. This is readily accomplished by filtration through sterile filtration membranes.

Sustained-release preparations can be prepared. Suitable examples of sustained-release preparations include semipermeable matrices of solid hydrophobic polymers containing the antibody, which matrices are in the form of shaped articles, e.g., films, or microcapsules. Examples of sustained-release matrices include polyesters, hydrogels (for example, poly(2-hydroxyethyl-methacrylate), or poly(vinylalcohol)), polylactides (U.S. Pat. No. 3,773,919), copolymers of L-glutamic acid and γ ethyl-L-glutamate, non-degradable ethylene-vinyl acetate, degradable lactic acid-glycolic acid copolymers such as the LUPRON DEPOT™ (injectable microspheres composed of lactic acid-glycolic acid copolymer and leuprolide acetate), and poly-D-(−)-3-hydroxybutyric acid. While polymers such as ethylene-vinyl acetate and lactic acid-glycolic acid enable release of molecules for over 100 days, certain hydrogels release proteins for shorter time periods.

ELISA Assay

An agent for detecting an analyte protein is an antibody capable of binding to an analyte protein, preferably an antibody with a detectable label. Antibodies can be polyclonal, or more preferably, monoclonal. An intact antibody, or a fragment thereof (e.g., F_(ab) or F_((ab)2)) can be used. The term “labeled”, with regard to the probe or antibody, is intended to encompass direct labeling of the probe or antibody by coupling (i.e., physically linking) a detectable substance to the probe or antibody, as well as indirect labeling of the probe or antibody by reactivity with another reagent that is directly labeled. Examples of indirect labeling include detection of a primary antibody using a fluorescently-labeled secondary antibody and end-labeling of a DNA probe with biotin such that it can be detected with fluorescently-labeled streptavidin. The term “biological sample” is intended to include tissues, cells and biological fluids isolated from a subject, as well as tissues, cells and fluids present within a subject. Included within the usage of the term “biological sample”, therefore, is blood and a fraction or component of blood including blood serum, blood plasma, or lymph. That is, the detection method of the invention can be used to detect an analyte mRNA, protein, or genomic DNA in a biological sample in vitro as well as in vivo. For example, in vitro techniques for detection of an analyte mRNA include Northern hybridizations and in situ hybridizations. In vitro techniques for detection of an analyte protein include enzyme linked immunosorbent assays (ELISAs), Western blots, imnuunoprecipitations, and immunofluorescence. In vitro techniques for detection of an analyte genomic DNA include Southern hybridizations. Procedures for conducting immunoassays are described, for example in “ELISA: Theory and Practice: Methods in Molecular Biology”, Vol. 42, J. R. Crowther (Ed.) Human Press, Totowa, N.J., 1995; “Immunoassay”, E. Diamandis and T. Christopoulus, Academic Press, Inc., San Diego, Calif., 1996; and “Practice and Thory of Enzyme Immunoassays”, P. Tijssen, Elsevier Science Publishers, Amsterdam. 1985. Furthermore, in vivo techniques for detection of an analyte protein include introducing into a subject a labeled anti-an analyte protein antibody. For example, the antibody can be labeled with a radioactive marker whose presence and location in a subject can be detected by standard imaging techniques.

SECX and/or NOVX Recombinant Expression Vectors and Host Cells

Another aspect of the invention pertains to vectors, preferably expression vectors, containing a nucleic acid encoding an SECX and/or NOVX protein, or derivatives, fragments, analogs or homologs thereof. As used herein, the term “vector” refers to a nucleic acid molecule capable of transporting another nucleic acid to which it has been linked. One type of vector is a “plasmid”, which refers to a circular double stranded DNA loop into which additional DNA segments can be ligated. Another type of vector is a viral vector, wherein additional DNA segments can be ligated into the viral genome. Certain vectors are capable of autonomous replication in a host cell into which they are introduced (e.g., bacterial vectors having a bacterial origin of replication and episomal mammalian vectors). Other vectors (e.g., non-episomal mammalian vectors) are integrated into the genome of a host cell upon introduction into the host cell, and thereby are replicated along with the host genome. Moreover, certain vectors are capable of directing the expression of genes to which they are operatively-linked. Such vectors are referred to herein as “expression vectors”. In general, expression vectors of utility in recombinant DNA techniques are often in the form of plasmids. In the present specification, “plasmid” and “vector” can be used interchangeably as the plasmid is the most commonly used form of vector. However, the invention is intended to include such other forms of expression vectors, such as viral vectors (e.g, replication defective retroviruses, adenoviruses and adeno-associated viruses), which serve equivalent functions.

The recombinant expression vectors of the invention comprise a nucleic acid of the invention in a form suitable for expression of the nucleic acid in a host cell, which means that the recombinant expression vectors include one or more regulatory sequences, selected on the basis of the host cells to be used for expression, that is operatively-linked to the nucleic acid sequence to be expressed. Within a recombinant expression vector, “operably-linked” is intended to mean that the nucleotide sequence of interest is linked to the regulatory sequence(s) in a manner that allows for expression of the nucleotide sequence (e.g., in an in vitro transcription/translation system or in a host cell when the vector is introduced into the host cell).

The term “regulatory sequence” is intended to includes promoters, enhancers and other expression control elements (e.g., polyadenylation signals). Such regulatory sequences are described, for example, in Goeddel, GENE EXPRESSION TECHNOLOGY: METHODS IN ENZYMOLOGY 185, Academic Press, San Diego, Calif. (1990). Regulatory sequences include those that direct constitutive expression of a nucleotide sequence in many types of host cell and those that direct expression of the nucleotide sequence only in certain host cells (e.g., tissue-specific regulatory sequences). It will be appreciated by those skilled in the art that the design of the expression vector can depend on such factors as the choice of the host cell to be transformed, the level of expression of protein desired, etc. The expression vectors of the invention can be introduced into host cells to thereby produce proteins or peptides, including fusion proteins or peptides, encoded by nucleic acids as described herein (e.g., SECX and/or NOVX proteins, mutant forms of SECX and/or NOVX proteins, fusion proteins, etc.).

The recombinant expression vectors of the invention can be designed for expression of SECX and/or NOVX proteins in prokaryotic or eukaryotic cells. For example, SECX and/or NOVX proteins can be expressed in bacterial cells such as Escherichia coli, insect cells (using baculovirus expression vectors) yeast cells or mammalian cells. Suitable host cells are discussed further in Goeddel, GENE EXPRESSION TECHNOLOGY: METHODS IN ENZYMOLOGY 185, Academic Press, San Diego, Calif. (1990). Alternatively, the recombinant expression vector can be transcribed and translated in vitro, for example using T7 promoter regulatory sequences and T7 polymerase.

Expression of proteins in prokaryotes is most often carried out in Escherichia coli with vectors containing constitutive or inducible promoters directing the expression of either fusion or non-fusion proteins. Fusion vectors add a number of amino acids to a protein encoded therein, usually to the amino terminus of the recombinant protein. Such fusion vectors typically serve three purposes: (i) to increase expression of recombinant protein; (ii) to increase the solubility of the recombinant protein; and (iii) to aid in the purification of the recombinant protein by acting as a ligand in affinity purification. Often, in fusion expression vectors, a proteolytic cleavage site is introduced at the junction of the fusion moiety and the recombinant protein to enable separation of the recombinant protein from the fusion moiety subsequent to purification of the fusion protein. Such enzymes, and their cognate recognition sequences, include Factor Xa, thrombin and enterokinase. Typical fusion expression vectors include pGEX (Pharmacia Biotech Inc; Smith and Johnson, 1988. Gene 67: 31-40), pMAL (New England Biolabs, Beverly, Mass.) and pRIT5 (Pharmacia, Piscataway, N.J.) that fuse glutathione S-transferase (GST), maltose E binding protein, or protein A, respectively, to the target recombinant protein.

Examples of suitable inducible non-fusion E. coli expression vectors include pTrc (Amrann et al., (1988) Gene 69:301-315) and pET 11d (Studier et al., GENE EXPRESSION TECHNOLOGY: METHODS IN ENZYMOLOGY, 185, Academic Press, San Diego, Calif. (1990) 60-89).

One strategy to maximize recombinant protein expression in E. coli is to express the protein in a host bacteria with an impaired capacity to proteolytically cleave the recombinant protein. See, e.g., Gottesman, GENE EXPRESSION TECHNOLOGY: METHODS IN ENZYMOLOGY 185, Academic Press, San Diego, Calif. (1990) 119-128. Another strategy is to alter the nucleic acid sequence of the nucleic acid to be inserted into an expression vector so that the individual codons for each amino acid are those preferentially utilized in E. coli (see, e.g., Wada, et al., 1992. Nucl. Acids Res. 20: 2111-2118). Such alteration of nucleic acid sequences of the invention can be carried out by standard DNA synthesis techniques.

In another embodiment, the SECX and/or NOVX expression vector is a yeast expression vector. Examples of vectors for expression in yeast Saccharomyces cerivisae include pYepSec1 (Baldari, et al., 1987. EMBO J. 6: 229-234), pMFa (Kurjan and Herskowitz, 1982. Cell 30: 933-943), pJRY88 (Schultz et al., 1987. Gene 54: 113-123), pYES2 (Invitrogen Corporation, San Diego, Calif.), and picZ (InVitrogen Corp, San Diego, Calif.).

Alternatively, SECX and/or NOVX can be expressed in insect cells using baculovirus expression vectors. Baculovirus vectors available for expression of proteins in cultured insect cells (e.g., SF9 cells) include the pAc series (Smith, et al., 1983. Mol. Cell. Biol. 3: 2156-2165) and the pVL series (Lucklow and Summers, 1989. Virology 170: 31-39).

In yet another embodiment, a nucleic acid of the invention is expressed in mammalian cells using a mammalian expression vector. Examples of mammalian expression vectors include pCDM8 (Seed, 1987. Nature 329: 840) and pMT2PC (Kaufman, et al., 1987. EMBO J. 6: 187-195). When used in mammalian cells, the expression vector's control functions are often provided by viral regulatory elements. For example, commonly used promoters are derived from polyoma, adenovirus 2, cytomegalovirus, and simian virus 40. For other suitable expression systems for both prokaryotic and eukaryotic cells see, e.g., Chapters 16 and 17 of Sambrook, et al., MOLECULAR CLONING: A LABORATORY MANUAL. 2nd ed., Cold Spring Harbor Laboratory, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989.

In another embodiment, the recombinant mammalian expression vector is capable of directing expression of the nucleic acid preferentially in a particular cell type (e.g., tissue-specific regulatory elements are used to express the nucleic acid). Tissue-specific regulatory elements are known in the art. Non-limiting examples of suitable tissue-specific promoters include the albumin promoter (liver-specific; Pinkert, et al., 1987. Genes Dev. 1: 268-277), lymphoid-specific promoters (Calame and Eaton, 1988. Adv. Immunol. 43: 235-275), in particular promoters of T cell receptors (Winoto and Baltimore 1989. EMBO J. 8: 729-733) and immunoglobulins (Banerji, et al., 1983. Cell 33: 729-740; Queen and Baltimore, 1983. Cell 33: 741-748), neuron-specific promoters (e.g., the neurofilament promoter; Byrne and Ruddle, 1989. Proc. Natl. Acad. Sci. USA 86: 5473-5477), pancreas-specific promoters (Edlund, et al., 1985. Science 230: 912-916), and mammary gland-specific promoters (e.g., milk whey promoter; U.S. Pat. No. 4,873,316 and European Application Publication No. 264,166). Developmentally-regulated promoters are also encompassed, e.g., the murine hox promoters (Kessel and Gruss, 1990. Science 249: 374-379) and the α-fetoprotein promoter (Campes and Tilghman, 1989. Genes Dev. 3: 537-546).

The invention further provides a recombinant expression vector comprising a DNA molecule of the invention cloned into the expression vector in an antisense orientation. That is, the DNA molecule is operatively-linked to a regulatory sequence in a manner that allows for expression (by transcription of the DNA molecule) of an RNA molecule that is antisense to SECX and/or NOVX mRNA. Regulatory sequences operatively linked to a nucleic acid cloned in the antisense orientation can be chosen that direct the continuous expression of the antisense RNA molecule in a variety of cell types, for instance viral promoters and/or enhancers, or regulatory sequences can be chosen that direct constitutive, tissue specific or cell type specific expression of antisense RNA. The antisense expression vector can be in the form of a recombinant plasmid, phagemid or attenuated virus in which antisense nucleic acids are produced under the control of a high efficiency regulatory region, the activity of which can be determined by the cell type into which the vector is introduced. For a discussion of the regulation of gene expression using antisense genes see, e.g., Weintraub, et al., “Antisense RNA as a molecular tool for genetic analysis,” Reviews—Trends in Genetics, Vol. 1(1) 1986.

Another aspect of the invention pertains to host cells into which a recombinant expression vector of the invention has been introduced. The terms “host cell” and “recombinant host cell” are used interchangeably herein. It is understood that such terms refer not only to the particular subject cell but also to the progeny or potential progeny of such a cell. Because certain modifications may occur in succeeding generations due to either mutation or environmental influences, such progeny may not, in fact, be identical to the parent cell, but are still included within the scope of the term as used herein.

A host cell can be any prokaryotic or eukaryotic cell. For example, SECX and/or NOVX protein can be expressed in bacterial cells such as E. coli, insect cells. east or mammalian cells (such as Chinese hamster ovary cells (CHO) or COS cells). Other suitable host cells are known to those skilled in the art.

Vector DNA can be introduced into prokaryotic or eukaryotic cells via conventional transformation or transfection techniques. As used herein, the terms “transformation” and “transfection” are intended to refer to a variety of art-recognized techniques for introducing foreign nucleic acid (e.g., DNA) into a host cell, including calcium phosphate or calcium chloride co-precipitation, DEAE-dextran-mediated transfection, lipofection, or electroporation. Suitable methods for transforming or transfecting host cells can be found in Sambrook, et al. (MOLECULAR CLONING: A LABORATORY MANUAL. 2nd ed., Cold Spring Harbor Laboratory, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989), and other laboratory manuals.

For stable transfection of mammalian cells, it is known that, depending upon the expression vector and transfection technique used, only a small fraction of cells may integrate the foreign DNA into their genome. In order to identify and select these integrants, a gene that encodes a selectable marker (e.g., resistance to antibiotics) is generally introduced into the host cells along with the gene of interest. Various selectable markers include those that confer resistance to drugs, such as G418, hygromycin and methotrexate. Nucleic acid encoding a selectable marker can be introduced into a host cell on the same vector as that encoding SECX and/or NOVX or can be introduced on a separate vector. Cells stably transfected with the introduced nucleic acid can be identified by drug selection (e.g., cells that have incorporated the selectable marker gene will survive, while the other cells die).

A host cell of the invention, such as a prokaryotic or eukaryotic host cell in culture, can be used to produce (i.e., express) SECX and/or NOVX protein. Accordingly, the invention further provides methods for producing SECX and/or NOVX protein using the host cells of the invention. In one embodiment, the method comprises culturing the host cell of invention (into which a recombinant expression vector encoding SECX and/or NOVX protein has been introduced) in a suitable medium such that SECX and/or NOVX protein is produced. In another embodiment, the method further comprises isolating SECX and/or NOVX protein from the medium or the host cell.

Transgenic SECX and/or NOVX Animals

The host cells of the invention can also be used to produce non-human transgenic animals. For example, in one embodiment, a host cell of the invention is a fertilized oocyte or an embryonic stem cell into which SECX and/or NOVX protein-coding sequences have been introduced. Such host cells can then be used to create non-human transgenic animals in which exogenous SECX and/or NOVX sequences have been introduced into their genome or homologous recombinant animals in which endogenous SECX and/or NOVX sequences have been altered. Such animals are useful for studying the function and/or activity of SECX and/or NOVX protein and for identifying and/or evaluating modulators of SECX and/or NOVX protein activity. As used herein, a “transgenic animal” is a non-human animal, preferably a mammal, more preferably a rodent such as a rat or mouse, in which one or more of the cells of the animal includes a transgene. Other examples of transgenic animals include non-human primates, sheep, dogs, cows, goats, chickens, amphibians, etc. A transgene is exogenous DNA that is integrated into the genome of a cell from which a transgenic animal develops and that remains in the genome of the mature animal, thereby directing the expression of an encoded gene product in one or more cell types or tissues of the transgenic animal. As used herein, a “homologous recombinant animal” is a non-human animal, preferably a mammal, more preferably a mouse, in which an endogenous SECX and/or NOVX gene has been altered by homologous recombination between the endogenous gene and an exogenous DNA molecule introduced into a cell of the animal, e.g., an embryonic cell of the animal, prior to development of the animal.

A transgenic animal of the invention can be created by introducing SECX and/or NOVX-encoding nucleic acid into the male pronuclei of a fertilized oocyte (e.g., by microinjection, retroviral infection) and allowing the oocyte to develop in a pseudopregnant female foster animal. The human SECX and/or NOVX cDNA sequences SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37and 39can be introduced as a transgene into the genome of a non-human animal. Alternatively, a non-human homologue of the human SECX and/or NOVX gene, such as a mouse SECX and/or NOVX gene, can be isolated based on hybridization to the human SECX and/or NOVX cDNA (described further supra) and used as a transgene. Intronic sequences and polyadenylation signals can also be included in the transgene to increase the efficiency of expression of the transgene. A tissue-specific regulatory sequence(s) can be operably-linked to the SECX and/or NOVX transgene to direct expression of SECX and/or NOVX protein to particular cells. Methods for generating transgenic animals via embryo manipulation and microinjection, particularly animals such as mice, have become conventional in the art and are described, for example, in U.S. Pat. Nos. 4,736,866; 4,870,009; and 4,873,191: and Hogan, 1986. In: MANIPULATING THE MOUSE EMBRYO, Cold Spring Harbor Laboratory, Press, Cold Spring Harbor, N.Y. Similar methods are used for production of other transgenic animals. A transgenic founder animal can be identified based upon the presence of the SECX and/or NOVX transgene in its genome and/or expression of SECX and/or NOVX mRNA in tissues or cells of the animals. A transgenic founder animal can then be used to breed additional animals carrying the transgene. Moreover, transgenic animals carrying a transgene-encoding SECX and/or NOVX protein can further be bred to other transgenic animals carrying other transgenes.

To create a homologous recombinant animal, a vector is prepared which contains at least a portion of an SECX and/or NOVX gene into which a deletion, addition or substitution has been introduced to thereby alter, e.g., functionally disrupt, the SECX and/or NOVX gene. The SECX and/or NOVX gene can be a human gene (e.g., the cDNA of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39), but more preferably, is a non-human homologue of a human SECX and/or NOVX gene. For example, a mouse homologue of human SECX and/or NOVX gene of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39 can be used to construct a homologous recombination vector suitable for altering an endogenous SECX and/or NOVX gene in the mouse genome. In one embodiment, the vector is designed such that, upon homologous recombination, the endogenous SECX and/or NOVX gene is functionally disrupted (i.e, no longer encodes a functional protein; also referred to as a “knock out” vector).

Alternatively, the vector can be designed such that, upon homologous recombination, the endogenous SECX and/or NOVX gene is mutated or otherwise altered but still encodes functional protein (e.g., the upstream regulatory region can be altered to thereby alter the expression of the endogenous SECX and/or NOVX protein). In the homologous recombination vector, the altered portion of the SECX and/or NOVX gene is flanked at its 5′- and 3′-termini by additional nucleic acid of the SECX and/or NOVX gene to allow for homologous recombination to occur between the exogenous SECX and/or NOVX gene carried by the vector and an endogenous SECX and/or NOVX gene in an embryonic stem cell. The additional flanking SECX and/or NOVX nucleic acid is of sufficient length for successful homologous recombination with the endogenous gene. Typically, several kilobases of flanking DNA (both at the 5′- and 3′-termini) are included in the vector. See, e.g., Thomas, et al., 1987. Cell 51: 503 for a description of homologous recombination vectors. The vector is ten introduced into an embryonic stem cell line (e.g., by electroporation) and cells in which the introduced SECX and/or NOVX gene has homologously-recombined with the endogenous SECX and/or NOVX gene are selected. See, e.g., Li, et al., 1992. Cell 69: 915.

The selected cells are then injected into a blastocyst of an animal (e.g., a mouse) to form aggregation chimeras. See, e.g., Bradley, 1987. In: TERATOCARCINOMAS AND EMBRYONIC STEM CELLS A PRACTICAL APPROACH, Robertson, ed. IRL, Oxford, pp.113-152. A chimeric embryo can then be implanted into a suitable pseudopregnant female foster animal and the embryo brought to term. Progeny harboring the homologously-recombined DNA in their germ cells can be used to breed animals in which all cells of the animal contain the homologously-recombined DNA by germline transmission of the transgene. Methods for constructing homologous recombination vectors and homologous recombinant animals are described further in Bradley, 1991. Curr. Opin. Biotechnol 2: 823-829; PCT International Publication Nos.: WO 90/11354; WO 91/01140; WO 92/0968; and WO 93/04169.

In another embodiment, transgenic non-humans animals can be produced that contain selected systems that allow for regulated expression of the transgene. One example of such a system is the cre/loxP recombinase system of bacteriophage P1. For a description of the cre/loxP recombinase system, See, e.g., Lakso, et al., 1992. Proc. Natl. Acad. Sci. USA 89: 6232-6236. Another example of a recombinase system is the FLP recombinase system of Saccharomyces cerevisiae. See, O'Gorman, et al., 1991. Science 251:1351-1355. If a cre/loxP recombinase system is used to regulate expression of the transgene, animals containing transgenes encoding both the Cre recombinase and a selected protein are required. Such animals can be provided through the construction of “double” transgenic animals, e.g., by mating two transgenic animals, one containing a transgene encoding a selected protein and the other containing a transgene encoding a recombinase.

Clones of the non-human transgenic animals described herein can also be produced according to the methods described in Wilmut, et al., 1997. Nature 385: 810-813. In brief. a cell (e.g., a somatic cell) from the transgenic animal can be isolated and induced to exit the growth cycle and enter G₀ phase. The quiescent cell can then be fused, e.g., through the use of electrical pulses, to an enucleated oocyte from an animal of the same species from which the quiescent cell is isolated. The reconstructed oocyte is then cultured such that it develops to morula or blastocyte and then transferred to pseudopregnant female foster animal. The offspring borne of this female foster animal will be a clone of the animal from which the cell (e.g., the somatic cell) is isolated.

Pharmaceutical Compositions

The SECX and/or NOVX nucleic acid molecules, SECX and/or NOVX proteins. and anti-SECX and/or NOVX antibodies (also referred to herein as “active compounds”) of the invention, and derivatives fragments, analogs and homologs thereof, can be incorporated into pharmaceutical compositions suitable for administration. Such compositions typically comprise the nucleic acid molecule, protein, or antibody and a pharmaceutically acceptable carrier. As used herein, “pharmaceutically acceptable carrier” is intended to include any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. Suitable carriers are described in the most recent edition of Remington's Pharmaceutical Sciences, a standard reference text in the field, which is incorporated herein by reference. Preferred examples of such carriers or diluents include, but are not limited to, water, saline, finger's solutions, dextrose solution, and 5% human serum albumin. Liposomes and non-aqueous vehicles such as fixed oils may also be used. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the compositions is contemplated. Supplementary active compounds can also be incorporated into the compositions.

A pharmaceutical composition of the invention is formulated to be compatible with its intended route of administration. Examples of routes of administration include parenteral, e.g., intravenous, intradermal, subcutaneous, oral (e.g., inhalation), transdermal (i.e., topical), transmucosal, and rectal administration. Solutions or suspensions used for parenteral, intradermal, or subcutaneous application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid (EDTA); buffers such as acetates, citrates or phosphates, and agents for the adjustment of tonicity such as sodium chloride or dextrose. The pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.

Pharmaceutical compositions suitable for injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor EL™ (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). In all cases, the composition must be sterile and should be fluid to the extent that easy syringeability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like). and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as manitol, sorbitol, sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.

Sterile injectable solutions can be prepared by incorporating the active compound (e.g., an SECX and/or NOVX protein or anti-SECX and/or NOVX antibody) in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle that contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation are vacuum drying and freeze-drying that yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

Oral compositions generally include an inert diluent or an edible carrier. They can be enclosed in gelatin capsules or compressed into tablets. For the purpose of oral therapeutic administration, the active compound can be incorporated with excipients and used in the form of tablets, troches, or capsules. Oral compositions can also be prepared using a fluid carrier for use as a mouthwash, wherein the compound in the fluid carrier is applied orally and swished and expectorated or swallowed. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition. The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.

For administration by inhalation, the compounds are delivered in the form of an aerosol spray from pressured container or dispenser which contains a suitable propellant, e.g., a gas such as carbon dioxide, or a nebulizer.

Systemic administration cam also be by transmucosal or transdermal means. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art, and include, for example, for transmucosal administration, detergents, bile salts, and fusidic acid derivatives. Transmucosal administration can be accomplished through the use of nasal sprays or suppositories. For transdermal administration, the active compounds are formulated into ointments, salves, gels, or creams as generally known in the art.

The compounds can also be prepared in the form of suppositories (e.g., with conventional suppository bases such as cocoa butter and other glycerides) or retention enemas for rectal delivery.

In one embodiment, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. The materials can also be obtained commercially from Alza Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811.

It is especially advantageous to formulate oral or parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of individuals.

The nucleic acid molecules of the invention can be inserted into vectors and used as gene therapy vectors. Gene therapy vectors can be delivered to a subject by, for example, intravenous injection, local administration (see, e.g., U.S. Pat. No. 5,328,470) or by stereotactic injection (see, e.g., Chen, et al., 1994. Proc. Natl. Acad Sci USA 91: 3054-3057). The pharmaceutical preparation of the gene therapy vector can include the gene therapy vector in an acceptable diluent, or can comprise a slow release matrix in which the gene delivery vehicle is imbedded. Alternatively, where the complete gene delivery vector can be produced intact from recombinant cells, e.g., retroviral vectors, the pharmaceutical preparation can include one or more cells that produce the gene delivery system.

The pharmaceutical compositions can be included in a container, pack, or dispenser together with instructions for administration.

Screening and Detection Methods

The isolated nucleic acid molecules of the invention can be used to express SECX and/or NOVX protein (e.g., via a recombinant expression vector in a host cell in gene therapy applications), to detect SECX and/or NOVX mRNA (e.g., in a biological sample) or a genetic lesion in an SECX and/or NOVX gene, and to modulate SECX and/or NOVX activity, as described further, below. In addition, the SECX and/or NOVX proteins can be used to screen drugs or compounds that modulate the SECX and/or NOVX protein activity or expression as well as to treat disorders characterized by insufficient or excessive production of SECX and/or NOVX protein or production of SECX and/or NOVX protein forms that have decreased or aberrant activity compared to SECX and/or NOVX wild-type protein (e.g.; diabetes (regulates insulin release); obesity (binds and transport lipids); metabolic disturbances associated with obesity, the metabolic syndrome X as well as anorexia and wasting disorders associated with chronic diseases and various cancers, and infectious disease(possesses anti-microbial activity) and the various dyslipidemias. In addition, the anti-SECX and/or NOVX antibodies of the invention can be used to detect and isolate SECX and/or NOVX proteins and modulate SECX and/or NOVX activity. In yet a further aspect, the invention can be used in methods to influence appetite, absorption of nutrients and the disposition of metabolic substrates in both a positive and negative fashion.

The invention further pertains to novel agents identified by the screening assays described herein and uses thereof for treatments as described, supra.

Screening Assays

The invention provides a method (also referred to herein as a “screening assay”) for identifying modulators, i.e., candidate or test compounds or agents (e.g, peptides, peptidomimetics, small molecules or other drugs) that bind to SECX and/or NOVX proteins or have a stimulatory or inhibitory effect on. e.g., SECX and/or NOVX protein expression or SECX and/or NOVX protein activity. The invention also includes compounds identified in the screening assays described herein.

In one embodiment, the invention provides assays for screening candidate or test compounds which bind to or modulate the activity of the membrane-bound form of an SECX and/or NOVX protein or polypeptride or biologically-active portion thereof. The test compounds of the invention can be obtained using any of the numerous approaches in combinatorial library methods known in the art, including: biological libraries; spatially addressable parallel solid phase or solution phase libraries; synthetic library methods requiring deconvolution; the “one-bead one-compound” library method; and synthetic library methods using affinity chromatography selection. The biological library approach is limited to peptide libraries, while the other four approaches are applicable to peptide, non-peptide oligomer or small molecule libraries of compounds. See, e.g., Lam, 1997. Anticancer Drug Design 12: 145.

A “small molecule” as used herein, is meant to refer to a composition that has a molecular weight of less than about 5 kD and most preferably less than about 4 kD. Small molecules can be, e.g., nucleic acids, peptides, polypeptides, peptidomimetics, carbohydrates, lipids or other organic or inorganic molecules. Libraries of chemical and/or biological mixtures, such as fungal, bacterial, or algal extracts, are known in the art and can be screened with any of the assays of the invention.

In one embodiment, an assay is a cell-based assay in which a cell which expresses a membrane-bound form of SECX and/or NOVX protein, or a biologically-active portion thereof, on the cell surface is contacted with a test compound and the ability of the test compound to bind to an SECX and/or NOVX protein determined. The cell, for example, can of mammalian origin or a yeast cell. Determining the ability of the test compound to bind to the SECX and/or NOVX protein can be accomplished, for example, by coupling the test compound with a radioisotope or enzymatic label such that binding of the test compound to the SECX and/or NOVX protein or biologically-active portion thereof can be determined by detecting the labeled compound in a complex. For example, test compounds can be labeled with ¹²⁵I, ³⁵S, ¹⁴C, or ³H, either directly or indirectly, and the radioisotope detected by direct counting of radioemission or by scintillation counting. Alternatively, test compounds can be enzymatically-labeled with, for example, horseradish peroxidase, alkaline phosphatase, or luciferase, and the enzymatic label detected by determination of conversion of an appropriate substrate to product. In one embodiment, the assay comprises contacting a cell which expresses a membrane-bound form of SECX and/or NOVX protein, or a biologically-active portion thereof, on the cell surface with a known compound which binds SECX and/or NOVX to form an assay mixture, contacting the assay mixture with a test compound, and determining the ability of the test compound to interact with an SECX and/or NOVX protein, wherein determining the ability of the test compound to interact with an SECX and/or NOVX protein comprises determining the ability of the test compound to preferentially bind to SECX and/or NOVX protein or a biologically-active portion thereof as compared to the known compound.

In another embodiment, am assay is a cell-based assay comprising contacting a cell expressing a membrane-bound form of SECX and/or NOVX protein, or a biologically-active portion thereof, on the cell surface with a test compound and determining the ability of the test compound to modulate (e.g., stimulate or inhibit) the activity of the SECX and/or NOVX protein or biologically-active portion thereof. Determining the ability of the test compound to modulate the activity of SECX and/or NOVX or a biologically-active portion thereof can be accomplished, for example, by determining the ability of the SECX and/or NOVX protein to bind to or interact with an SECX and/or NOVX target molecule. As used herein, a “target molecule” is a molecule with which an SECX and/or NOVX protein binds or interacts in nature, for example, a molecule on the surface of a cell which expresses an SECX and/or NOVX interacting protein, a molecule on the surface of a second cell, a molecule in the extracellular milieu. a molecule associated with the internal surface of a cell membrane or a cytoplasmic molecule. An SECX and/or NOVX target molecule can be a non-SECX and/or NOVX molecule or an SECX and/or NOVX protein or polypeptide of the invention. In one embodiment, an SECX and/or NOVX target molecule is a component of a signal transduction pathway that facilitates transduction of an extracellular signal (e.g. a signal generated by binding of a compound to a membrane-bound SECX and/or NOVX molecule) through the cell membrane and into the cell. The target, for example, can be a second intercellular protein that has catalytic activity or a protein that facilitates the association of downstream signaling molecules with SECX and/or NOVX.

Determining the ability of the SECX and/or NOVX protein to bind to or interact with an SECX and/or NOVX target molecule can be accomplished by one of the methods described above for determining direct binding. In one embodiment, determining the ability of the SECX and/or NOVX protein to bind to or interact with an SECX and/or NOVX target molecule can be accomplished by determining the activity of the target molecule. For example, the activity of the target molecule can be determined by detecting induction of a cellular second messenger of the target (i.e. intracellular Ca²⁺, diacylglycerol, IP₃, etc.), detecting catalytic/enzymatic activity of the target an appropriate substrate, detecting the induction of a reporter gene (comprising an SECX and/or NOVX-responsive regulatory element operatively linked to a nucleic acid encoding, a detectable marker, e.g., luciferase), or detecting a cellular response, for example, cell survival, cellular differentiation, or cell proliferation.

In yet another embodiment, an assay of the invention is a cell-free assay comprising contacting an SECX and/or NOVX protein or biologically-active portion thereof with a test compound and determining the ability of the test compound to bind to the SECX and/or NOVX protein or biologically-active portion thereof. Binding of the test compound to the SECX and/or NOVX protein can be determined either directly or indirectly as described above. In one such embodiment, the assay comprises contacting the SECX and/or NOVX protein or biologically-active portion thereof with a known compound which binds SECX and/or NOVX to form an assay mixture, contacting the assay mixture with a test compound, and determining the ability of the test compound to interact with an SECX and/or NOVX protein, wherein determining the ability of the test compound to interact with an SECX and/or NOVX protein comprises determining the ability of the test compound to preferentially bind to SECX and/or NOVX or biologically-active portion thereof as compared to the known compound.

In still another embodiment, an assay is a cell-free assay comprising contacting SECX and/or NOVX protein or biologically-active portion thereof with a test compound and determining the ability of the test compound to modulate (e.g. stimulate or inhibit) the activity of the SECX and/or NOVX protein or biologically-active portion thereof. Determining the ability of the test compound to modulate the activits of SECX and/or NOVX can be accomplished, for example, by determining the ability of the SECX and/or NOVX protein to bind to an SECX and/or NOVX target molecule by one of the methods described above for determining direct binding. In an alternative embodiment, determining the ability of the test compound to modulate the activity of SECX and/or NOVX protein can be accomplished by determining the ability of the SECX and/or NOVX protein further modulate an SECX and/or NOVX target molecule. For example, the catalytic/enzymatic activity of the target molecule on an appropriate substrate can be determined as described, supra.

In yet another embodiment, the cell-free assay comprises contacting the SECX and/or NOVX protein or biologically-active portion thereof with a known compound which binds SECX and/or NOVX protein to form an assay mixture, contacting the assay mixture with a test compound, and determining the ability of the test compound to interact with an SECX and/or NOVX protein, wherein determining the ability of the test compound to interact with an SECX and/or NOVX protein comprises determining the ability of the SECX and/or NOVX protein to preferentially bind to or modulate the activity of an SECX and/or NOVX target molecule.

The cell-free assays of the invention are amenable to use of both the soluble form or the membrane-bound form of SECX and/or NOVX protein. In the case of cell-free assays comprising the membrane-bound form of SECX and/or NOVX protein, it may be desirable to utilize a solubilizing agent such that the membrane-bound form of SECX and/or NOVX protein is maintained in solution. Examples of such solubilizing agents include non-ionic detergents such as n-octylglucoside, n-dodecylglucoside, n-dodecylmaltoside, octanoyl-N-methylglucamide, decanoyl-N-methylglucamide, Triton® X-100, Triton® X-114, Thesit®, Isotridecypoly(ethylene glycol ether)_(n), N-dodecyl—N,N-dimethyl-3-ammonio-1-propane sulfonate, 3-(3-cholamidopropyl) dimethylamminiol-1-propane sulfonate (CHAPS), or 3-(3-cholamidopropyl)dimethylamnminiol-2-hydroxy-1-propane sulfonate (CHAPSO).

In more than one embodiment of the above assay methods of the invention, it may be desirable to immobilize either SECX and/or NOVX protein or its target molecule to facilitate separation of complexed from uncomplexed forms of one or both of the proteins, as well as to accommodate automation of the assay. Binding of a test compound to SECX and/or NOVX protein, or interaction of SECX and/or NOVX protein with a target molecule in the presence and absence of a candidate compound, can be accomplished in any vessel suitable for containing the reactants. Examples of such vessels include microtiter plates, test tubes. and micro-centrifuge tubes. In one embodiment, a fusion protein can be provided that adds a domain that allows one or both of the proteins to be bound to a matrix. For example, GST-SECX and/or NOVX fusion proteins or GST-target fusion proteins can be adsorbed onto glutathione sepharose beads (Sigma Chemical, St. Louis, Mo.) or glutathione derivatized microtiter plates, that are then combined with the test compound or the test compound and either the non-adsorbed target protein or SECX and/or NOVX protein, and the mixture is incubated under conditions conducive to complex formation (e.g., at physiological conditions for salt and pH). Following incubation, the beads or microtiter plate wells are washed to remove any unbound components, the matrix immobilized in the case of beads, complex determined either directly or indirectly, for example, as described, supra. Alternatively, the complexes can be dissociated from the matrix, and the level of SECX and/or NOVX protein binding or activity determined using standard techniques.

Other techniques for immobilizing proteins on matrices can also be used in the screening assays of the invention. For example, either the SECX and/or NOVX protein or its target molecule can be immobilized utilizing conjugation of biotin and streptavidin. Biotinylated SECX and/or NOVX protein or target molecules can be prepared from biotin-NHS (N-hydroxy-succiniinide) using techniques well-known within the art (e.g., biotinylation kit, Pierce Chemicals, Rockford, Ill.), and immobilized in the wells of streptavidin-coated 96 well plates (Pierce Chemical). Alternatively, antibodies reactive with SECX and/or NOVX protein or target molecules, but which do not interfere with binding of the SECX and/or NOVX protein to its target molecule, can be derivatized to the wells of the plate, and unbound target or SECX and/or NOVX protein trapped in the wells by antibody conjugation. Methods for detecting such complexes, in addition to those described above for the GST-immobilized complexes, include inimunodetection of complexes using antibodies reactive with the SECX and/or NOVX protein or target molecule, as well as enzyme-linked assays that rely on detecting an enzymatic activity associated with the SECX and/or NOVX protein or target molecule.

In another embodiment, modulators of SECX and/or NOVX protein expression are identified in a method wherein a cell is contacted with a candidate compound and the expression of SECX and/or NOVX mRNA or protein in the cell is determined. The level of expression of SECX and/or NOVX mRNA or protein in the presence of the candidate compound is compared to the level of expression of SECX and/or NOVX mRNA or protein in the absence of the candidate compound. The candidate compound can then be identified as a modulator of SECX and/or NOVX mRNA or protein expression based upon this comparison. For example, when expression of SECX and/or NOVX mRNA or protein is greater (i.e. statistically significantly greater) in the presence of the candidate compound than in its absence, the candidate compound is identified as a stimulator of SECX and/or NOVX mRNA or protein expression. Alternatively, when expression of SECX and/or NOVX mRNA or protein is less (statistically significantly less) in the presence of the candidate compound than in its absence, the candidate compound is identified as an inhibitor of SECX and/or NOVX mRNA or protein expression. The level of SECX and/or NOVX mRNA or protein expression in the cells can be determined by methods described herein for detecting SECX and/or NOVX mRNA or protein.

In yet another aspect of the invention, the SECX and/or NOVX proteins can be used as “bait proteins” in a two-hybrid assay or three hybrid assay (see, e.g., U.S. Pat. No. 5,283,317; Zervos, et al., 1993. Cell 72: 223-232; Madura, et al., 1993. J. Biol. Chem. 268: 12046-12054; Bartel, et al., 1993. Biotechniques 14: 920-924; Iwabuchi, et al., 1993. Oncogene 8: 1693-1696; and Brent WO 94/10300), to identify other proteins that bind to or interact with SECX and/or NOVX (“SECX and/or NOVX-binding proteins” or “SECX and/or NOVX-bp”) and modulate SECX and/or NOVX activity. Such SECX and/or NOVX-binding proteins are also likely to be involved in the propagation of signals by the SECX and/or NOVX proteins as, for example, upstream or downstream elements of the SECX and/or NOVX pathway.

The two-hybrid system is based on the modular nature of most transcription factors, which consist of separable DNA-binding and activation domains. Briefly, the assay utilizes two different DNA constructs. In one construct, the gene that codes for SECX and/or NOVX is fused to a gene encoding the DNA binding domain of a known transcription factor (e.g., GAL-4). In the other construct, a DNA sequence, from a library of DNA sequences, that encodes an unidentified protein (“prey” or “sample”) is fused to a gene that codes for the activation domain of the known transcription factor. If the “bait” and the “prey” proteins are able to interact, in vivo, forming an SECX and/or NOVX-dependent complex, the DNA-binding and activation domains of the transcription factor are brought into close proximity. This proximity allows transcription of a reporter gene (e.g., LacZ) that is operably linked to a transcriptional regulatory site responsive to the transcription factor. Expression of the reporter gene can be detected and cell colonies containing the functional transcription factor can be isolated and used lo obtain the cloned gene that encodes the protein which interacts with SECX and/or NOVX.

The invention further pertains to novel agents identified by the aforementioned screening assays and uses thereof for treatments as described herein.

Detection Assays

Portions or fragments of the cDNA sequences identified herein (and the corresponding complete gene sequences) can be used in numerous ways as polynucleotide reagents. By way of example, and not of limitation, these sequences can be used to: (i) map their respective genes on a chromosome; and, thus, locate gene regions associated with genetic disease; (ii) identify an individual from a minute biological sample (tissue typing); and (iii) aid in forensic identification of a biological sample. Some of these applications are described in the subsections, below.

Chromosome Mapping

Once the sequence (or a portion of the sequence) of a gene has been isolated, this sequence can be used to map the location of the gene on a chromosome. This process is called chromosome mapping. Accordingly, portions or fragments of the SECX and/or NOVX sequences, SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, or fragments or derivatives thereof, can be used to map the location of the SECX and/or NOVX genes, respectively, on a chromosome. The mapping of the SECX and/or NOVX sequences to chromosomes is an important first step in correlating these sequences with genes associated with disease.

Briefly, SECX and/or NOVX genes can be mapped to chromosomes by preparing PCR primers (preferably 15-25 bp in Length) from the SECX and/or NOVX sequences. Computer analysis of the SECX and/or NOVX, sequences can be used to rapidly select primers that do not span more than one exon in the genomic DNA, thus complicating the amplification process. These primers can then be used for PCR screening of somatic cell hybrids containing individual human chromosomes. Only those hybrids containing the human gene corresponding to the SECX and/or NOVX sequences will yield an amplified fragment.

Somatic cell hybrids are prepared by fusing somatic cells from different mammals (e.g., human and mouse cells). As hybrids of human and mouse cells grow and divide, they gradually lose human chromosomes in random order, but retain the mouse chromosomes. By using media in which mouse cells cannot grow, because they lack a particular enzyme, but in which human cells can, the one human chromosome that contains the gene encoding the needed enzyme will be retained. By using various media, panels of hybrid cell lines can be established. Each cell line in a panel contains either a single human chromosome or a small number of human chromosomes. and a fill set of mouse chromosomes, allowing easy mapping of individual genes to specific human chromosomes See, e.g., D'Eustachio, et al., 1983. Science 220: 919-924. Somatic cell hybrids containing only fragments of human chromosomes can also be produced by using human chromosomes with translocations and deletions.

PCR mapping of somatic cell hybrids is a rapid procedure for assigning a particular sequence to a particular chromosome. Three or more sequences can be assigned per day using a single thermal cycler. Using the SECX and/or NOVX sequences to design oligonucleotide primers, sub-localization can be achieved with panels of fragments from specific chromosomes.

Fluorescence in situ hybridization (FISH) of a DNA sequence to a metaphase chromosomal spread can further be used to provide a precise chromosomal location in one step. Chromosome spreads can be made using cells whose division has been blocked in metaphase by a chemical like colcemid that disrupts the mitotic spindle. The chromosomes can be treated briefly with trypsin, and then stained with Giemsa. A pattern of light and dark bands develops on each chromosome, so that the chromosomes can be identified individually. The FISH technique can be used with a DNA sequence as short as 500 or 600 bases. However, clones larger than 1,000 bases have a higher likelihood of binding to a unique chromosomal location with sufficient signal intensity for simple detection. Preferably 1,000 bases, and more preferably 2,000 bases, will suffice to get good results at a reasonable amount of time. For a review of this technique, see, Verma, et al., HUMAN CHROMOSOMES: A MANUAL OF BASIC TECHNIQUES (Pergamon Press, New York 1988).

Reagents for chromosome mapping can be used individually to mark a single chromosome or a single site on that chromosome, or panels of reagents can be used for marking multiple sites and/or multiple chromosomes. Reagents corresponding to noncoding regions of the genes actually are preferred for mapping purposes. Coding sequences are more likely to be conserved within gene families, thus increasing the chance of cross hybridizations during chromosomal mapping.

Once a sequence has been mapped to a precise chromosomal location, the physical position of the sequence on the chromosome can be correlated with genetic map data. Such data are found, e.g., in McKusick, MENDELIAN INHERITANCE IN MAN, available on-line through Johns Hopkins University Welch Medical Library). The relationship between genes and disease, mapped to the same chromosomal region, can then be identified through linkage analysis (co-inheritance of physically adjacent genes), described in. e.g., Egeland, et al., 1987. Nature, 325: 783-787.

Moreover, differences in the DNA sequences between individuals affected and unaffected with a disease associated with the SECX and/or NOVX gene, can be determined. If a mutation is observed in some or all of the affected individuals but not in any unaffected individuals, then the mutation is likely to be the causative agent of the particular disease. Comparison of affected and unaffected individuals generally involves first looking for structural alterations in the chromosomes, such as deletions or translocations that are visible from chromosome spreads or detectable using PCR based on that DNA sequence. Ultimately, complete sequencing of genes from several individuals can be performed to confirm the presence of a mutation and to distinguish mutations from polymorphisms.

Tissue Typing

The SECX and/or NOVX sequences of the invention can also be used to identify individuals from minute biological samples. In this technique, an individual's genomic DNA is digested with one or more restriction enzymes, and probed on a Southern blot to yield unique bands for identification. The sequences of the invention are useful as additional DNA markers for RFLP (“restriction fragment length polymorphisms,” described in U.S. Pat. No. 5,272,057).

Furthermore, the sequences of the invention can be used to provide an alternative technique that determines the actual base-by-base DNA sequence of selected portions of an individual's genome. Thus, the SECX and/or NOVX sequences described herein can be used to prepare two PCR primers from the 5′- and 3′-termini of the sequences. These primers can then be used to amplify an individual's DNA and subsequently sequence it.

Panels of corresponding DNA sequences from individuals, prepared in this manner, can provide unique individual identifications, as each individual will have a unique set of such DNA sequences due to allelic differences. The sequences of the invention can be used to obtain such identification sequences from individuals and from tissue. The SECX and/or NOVX sequences of the invention uniquely represent portions of the human genome. Allelic variation occurs to some degree in the coding regions of these sequences, and to a greater degree in the noncoding regions. It is estimated that allelic variation between individual humans occurs with a frequency of about once per each 500 bases. Much of the allelic variation is due to single nucleotide polymorphisms (SNPs), which include restriction fragment length polymorphisms (RFLPs).

Each of the sequences described herein can, to some degree. be used as a standard against which DNA from an individual can be compared for identification purposes. Because greater numbers of polymorphisms occur in the noncoding regions, fewer sequences are necessary to differentiate individuals. The noncoding sequences can comfortably provide positive individual identification with a panel of perhaps 10 to 1,000 primers that each yield a noncoding amplified sequence of 100 bases. If predicted coding sequences, such as those in SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37and 39 are used, a more appropriate number of primers for positive individual identification would be 500-2,000.

Predictive Medicine

The invention also pertains to the field of predictive medicine in which diagnostic assays, prognostic assays, pharmacogenomics, and monitoring clinical trials are used for prognostic (predictive) purposes to thereby treat an individual prophylactically. Accordingly, one aspect of the invention relates to diagnostic assays for determining SECX and/or NOVX protein and/or nucleic acid expression as well as SECX and/or NOVX activity, in the context of a biological sample (e.g., blood, serum, cells, tissue) to thereby determine whether an individual is afflicted with a disease or disorder, or is at risk of developing a disorder, associated with aberrant SECX and/or NOVX expression or activity. The disorders include metabolic disorders, diabetes, obesity, infectious disease, anorexia, cancer-associated cachexia, cancer, neurodegenerative disorders, Alzheimer's Disease, Parkinson's Disorder, immune disorders, and hematopoietic disorders, and the various dyslipidemias, metabolic disturbances associated with obesity, the metabolic syndrome X and wasting disorders associated with chronic diseases and various cancers. The invention also provides for prognostic (or predictive) assays for determining whether an individual is at risk of developing a disorder associated with SECX and/or NOVX protein, nucleic acid expression or activity. For example, mutations in an SECX and/or NOVX gene can be assayed in a biological sample. Such assays can be used for prognostic or predictive purpose to thereby prophylactically treat an individual prior to the onset of a disorder characterized by or associated with SECX and/or NOVX protein, nucleic acid expression, or biological activity.

Another aspect of the invention provides methods for determining SECX and/or NOVX protein, nucleic acid expression or activity in an individual to thereby select appropriate therapeutic or prophylactic agents for that individual (referred to herein as “pharmacogenomics”). Pharmacogenomics allows for the selection of agents (e.g., drugs) for therapeutic or prophylactic treatment of an individual based on the genotype of the individual (e.g., the genotype of the individual examined to determine the ability of the individual to respond to a particular agent.)

Yet another aspect of the invention pertains to monitoring the influence of agents (e.g., drugs, compounds) on the expression or activity of SECX and/or NOVX in clinical trials.

These and other agents are described in further detail in the following sections.

Diagnostic Assays

An exemplary method for detecting the presence or absence of SECX and/or NOVX in a biological sample involves obtaining a biological sample from a test subject and contacting the biological sample with a compound or an agent capable of detecting SECX and/or NOVX protein or nucleic acid (e.g., mRNA, genomic DNA) that encodes SECX and/or NOVX protein such that the presence of SECX and/or NOVX is detected in the biological sample. An agent for detecting SECX and/or NOVX mRNA or genomic DNA is a labeled nucleic acid probe capable of hybridizing to SECX and/or NOVX mRNA or genomic DNA. The nucleic acid probe can be, for example, a full-length SECX and/or NOVX nucleic acid, such as the nucleic acid of SEQ ID NOS:1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 and 39, or a portion thereof, such as an oligonucleotide of at least 15, 30, 50, 100, 250 or 500 nucleotides in length and sufficient to specifically hybridize under stringent conditions to SECX and/or NOVX mRNA or genomic DNA. Other suitable probes for use in the diagnostic assays of the invention are described herein.

An agent for detecting SECX and/or NOVX protein is an antibody capable of binding to SECX and/or NOVX protein, preferably an antibody with a detectable label. Antibodies can be polyclonal, or more preferably, monoclonal. An intact antibody, or a fragment thereof (e.g., Fab or F(ab′)₂) can be used. The term “labeled”, with regard to the probe or antibody, is intended to encompass direct labeling of the probe or antibody by coupling (i.e., physically linking) a detectable substance to the probe or antibody, as well as indirect labeling of the probe or antibody by reactivity with another reagent that is directly labeled. Examples of indirect labeling include detection of a primary antibody using a fluorescently-labeled secondary antibody and end-labeling of a DNA probe with biotin such that it can be detected with fluorescently-labeled streptavidin. The term “biological sample” is intended to include tissues, cells and biological fluids isolated from a subject, as well as tissues. cells and fluids present within a subject. That is, the detection method of the invention can be used to detect SECX and/or NOVX mRNA, protein, or genomic DNA in a biological sample in vitro as well as in vivo. For example, in vitro techniques for detection of SECX and/or NOVX mRNA include Northern hybridizations and in situ hybridizations. In vitro techniques for detection of SECX and/or NOVX protein include enzyme linked immunosorbent assays (ELISAs), Western blots, imnuunoprecipitations, and immunofluorescence. In vitro techniques for detection of SECX and/or NOVX genomic DNA include Southern hybridizations. Furthermore, in vivo techniques for detection of SECX and/or NOVX protein include introducing into a subject a labeled anti-SECX and/or NOVX antibody. For example, the antibody can be labeled with a radioactive marker whose presence and location in a subject can be detected by standard imaging techniques.

In one embodiment, the biological sample contains protein molecules from the test subject. Alternatively, the biological sample can contain mRNA molecules from the test subject or genomic DNA molecules from the test subject. A preferred biological sample is a peripheral blood leukocyte sample isolated by conventional means from a subject.

In another embodiment, the methods further involve obtaining a control biological sample from a control subject, contacting the control sample with a compound or agent capable of detecting SECX and/or NOVX protein, mRNA, or genomic DNA, such that the presence of SECX and/or NOVX protein, mRNA or genomic DNA is detected in the biological sample, and comparing the presence of SECX and/or NOVX protein, mRNA or genomic DNA in the control sample with the presence of SECX and/or NOVX protein, mRNA or genomic DNA in the test sample.

The invention also encompasses kits for detecting the presence of SECX and/or NOVX in a biological sample. For example, the kit can comprise: a labeled compound or agent capable of detecting SECX and/or NOVX protein or mRNA in a biological sample; means for determining the amount of SECX and/or NOVX in the sample; and means for comparing the amount of SECX and/or NOVX in the sample with a standard. The compound or agent can be packaged in a suitable container. The kit can further comprise instructions for using the kit to detect SECX and/or NOVX protein or nucleic acid.

Prognostic Assays

The diagnostic methods described herein can furthermore be utilized to identify subjects having or at risk of developing a disease or disorder associated with aberrant SECX and/or NOVX expression or activity. For example, the assays described herein, such as the preceding diagnostic assays or the following assays, can be utilized to identify a subject having or at risk of developing a disorder associated with SECX and/or NOVX protein, nucleic acid expression or activity. Alternatively, the prognostic assays can be utilized to identify a subject having or at risk. for developing a disease or disorder. Thus, the invention provides a method for identifying a disease or disorder associated with aberrant SECX and/or NOVX expression or activity in which a test sample is obtained from a subject and SECX and/or NOVX protein or nucleic acid (e.g., mRNA, genomic DNA) is detected, wherein the presence of SECX and/or NOVX protein or nucleic acid is diagnostic for a subject having or at risk of developing a disease or disorder associated with aberrant SECX and/or NOVX expression or activity. As used herein, a “test sample” refers to a biological sample obtained from a subject of interest. For example, a test sample can be a biological fluid (e.g., serum), cell sample, or tissue.

Furthermore, the prognostic assays described herein can be used to determine whether a subject can be administered an agent (e.g., an agonist, antagonist, peptidomimetic, protein, peptide, nucleic acid, small molecule, or other drug candidate) to treat a disease or disorder associated with aberrant SECX and/or NOVX expression or activity. For example, such methods can be used to determine whether a subject can be effectively treated with an agent for a disorder. Thus, the invention provides methods for determining whether a subject can be effectively treated with an agent for a disorder associated with aberrant SECX and/or NOVX expression or activity in which a test sample is obtained and SECX and/or NOVX protein or nucleic acid is detected (e.g., wherein the presence of SECX and/or NOVX protein or nucleic acid is diagnostic for a subject that can be administered the agent to treat a disorder associated with aberrant SECX and/or NOVX expression or activity).

The methods of the invention can also be used to detect genetic lesions in an SECX and/or NOVX gene, thereby determining if a subject with the lesioned gene is at risk for a disorder characterized by aberrant cell proliferation and/or differentiation. In various embodiments, the methods include detecting, in a sample of cells from the subject, the presence or absence of a genetic lesion characterized by at least one of an alteration affecting the integrity of a gene encoding an SECX and/or NOVX-protein, or the misexpression of the SECX and/or NOVX gene. For example, such genetic lesions can be detected by ascertaining the existence of at least one of: (i) a deletion of one or more nucleotides from an SECX and/or NOVX gene; (ii) an addition of one or more nucleotides to an SECX and/or NOVX gene; (iii) a substitution of one or more nucleotides of an SECX and/or NOVX gene, (iv) a chromosomal rearrangement of an SECX and/or NOVX gene; (v) an alteration in the level of a messenger RNA transcript of an SECX and/or NOVX gene, (vi) aberrant modification of an SECX and/or NOVX gene, such as of the methylation pattern of the genomic DNA, (vii) the presence of a non-wild-type splicing pattern of a messenger RNA transcript of an SECX and/or NOVX gene, (viii) a non-wild-type level of an SECX and/or NOVX protein, (ix) allelic loss of an SECX and/or NOVX gene, and (x) inappropriate post-translational modification of an SECX and/or NOVX protein. As described herein, there are a large number of assay techniques known in the art which can be used for detecting lesions in an SECX and/or NOVX gene. A preferred biological sample is a peripheral blood leukocyte sample isolated by conventional means from a subject. However, any biological sample containing nucleated cells may be used, including, for example, buccal mucosal cells.

In certain embodiments, detection of the lesion involves the use of a probe/primer in a polymerase chain reaction (PCR) (see, e.g., U.S. Pat. Nos. 4,683,195 and 4,683,202), such as anchor PCR or RACE PCR, or, alternatively, in a ligation chain reaction (LCR) (see, e.g., Landegran, et al., 1988. Science 241: 1077-1080; and Nakazawa, et al., 1994. Proc. Natl. Acad. Sci. USA 91: 360-364), the latter of which can be particularly useful for detecting point mutations in the SECX and/or NOVX-gene (see, Abravaya, et al., 1995. Nucl. Acids Res. 23: 675-682). This method can include the steps of collecting a sample of cells from a patient, isolating nucleic acid (e.g., genomic, mRNA or both) from the cells of the sample, contacting the nucleic acid sample with one or more primers that specifically hybridize to an SECX and/or NOVX gene under conditions such that hybridization and amplification of the SECX and/or NOVX gene (if present) occurs, and detecting the presence or absence of an amplification product, or detecting the size of the amplification product and comparing the length to a control sample. It is anticipated that PCR and/or LCR may be desirable to use as a preliminary amplification step in conjunction with any of the techniques used for detecting mutations described herein.

Alternative amplification methods include: self sustained sequence replication (see, Guatelli, et al., 1990. Proc. Natl. Acad. Sci. USA 87: 1874-1878), transcriptional amplification system (see, Kwoh, et al., 1989. Proc. Natl. Acad. Sci USA 86: 1173-1177); Qβ Replicase (see, Lizardi, et al, 1988. BioTechnology 6: 1197), or any other nucleic acid amplification method, followed by the detection of the amplified molecules using techniques well known to those of skill in the art. These detection schemes are especially useful for the detection of nucleic acid molecules if such molecules are present in very low numbers.

In an alternative embodiment, mutations in an SECX and/or NOVX gene from a sample cell can be identified by alterations in restriction enzyme cleavage patterns. For example, sample and control DNA is isolated, amplified (optionally), digested with one or more restriction endonucleases, and fragment length sizes are determined by gel electrophoresis and compared. Differences in fragment length sizes between sample and control DNA indicates mutations in the sample DNA. Moreover, the use of sequence specific ribozymes (see, e.g., U.S. Pat. No. 5,493,531) can be used to score for the presence of specific mutations by development or loss of a ribozyme cleavage site.

In other embodiments, genetic mutations in SECX and/or NOVX can be identified by hybridizing a sample and control nucleic acids, e.g., DNA or RNA, to high-density arrays containing hundreds or thousands of oligonucleotides probes. See, e.g., Cronin, et al., 1996. Human Mutation 7: 244-255; Kozal, et al., 1996. Nat. Med. 2: 753-759. For example, genetic mutations in SECX and/or NOVX can be identified in two dimensional arrays containing light-generated DNA probes as described in Cronin, et al., supra. Briefly, a first hybridization array of probes can be used to scan through long stretches of DNA in a sample and control to identify base changes between the sequences by making linear arrays of sequential overlapping probes. This step allows the identification of point mutations. This is followed by a second hybridization array that allows the characterization of specific mutations by using smaller, specialized probe arrays complementary to all variants or mutations detected. Each mutation array is composed of parallel probe sets, one complementary to the wild-type gene and the other complementary to the mutant gene.

In yet another embodiment, any of a variety of sequencing reactions known in the art can be used to directly sequence the SECX and/or NOVX gene and detect mutations by comparing the sequence of the sample SECX and/or NOVX with the corresponding wild-type (control) sequence. Examples of sequencing reactions include those based on techniques developed by Maxim and Gilbert, 1977. Proc. Natl. Acad. Sci. USA 74: 560 or Sanger, 1977. Proc. Natl. Acad. Sci. USA 74: 5463. It is also contemplated that any of a variety of automated sequencing procedures can be utilized when performing the diagnostic assays (see, e.g., Naeve, et al., 1995. Biotechniques 19: 448), including sequencing by mass spectrometry (see, e.g., PCT International Publication No. WO 94/16101. Cohen, et al., 1996. Adv. Chromatography 36: 127-162; and Griffin, et al., 1993. Appl. Biochem. Biotechnol. 38: 147-159).

Other methods for detecting mutations in the SECX and/or NOVX gene include methods in which protection from cleavage agents is used to detect mismatched bases in RNA/RNA or RNA/DNA heteroduplexes. See, e.g., Myers. et. al., 1985. Science 230:1242. In general, the art technique of “mismatch cleavage” starts by providing heteroduplexes of formed by hybridizing (labeled) RNA or DNA containing the wildype SECX and/or NOVX sequence with potentially mutant RNA or DNA obtained from a tissue sample. The double-stranded duplexes are treated with an agent that cleaves single-stranded regions of the duplex such as which will exist due to basepair mismatches between the control and sample strands. For instance, RNA/DNA duplexes can be treated with RNase and DNA/DNA hybrids treated with S₁ nuclease to enzymatically digesting the mismatched regions. In other embodiments, either DNA/DNA or RNA/DNA duplexes can be treated with hydroxylamine or osmium tetroxide and with piperildine in order to digest mismatched regions. After digestion of the mismatched regions, the resulting material is then separated by size on denaturing polyacrylamide gels to determine the site of mutation. See, e.g., Cotton, et al., 1988. Proc. Natl. Acad. Sci. USA 85: 4397; Saleeba, et al., 1992. Methods Enzymol. 217: 286-295. In an embodiment, the control DNA or RNA can be labeled for detection.

In still another embodiment, the mismatch cleavage reaction employs one or more proteins that recognize mismatched base pairs in double-stranded DNA (so called “DNA mismatch repair” enzymes) in defined systems for detecting and mapping point mutations in SECX and/or NOVX cDNAs obtained from samples of cells. For example, the mutY enzyme of E. coli cleaves A at G/A mismatches and the thymidine DNA glycosylase from HeLa cells cleaves T at G/T mismatches. See, e.g., Hsu, et al., 1994. Carcinogenesis 15: 1657-1662. According to an exemplary embodiment, a probe based on an SECX and/or NOVX sequence, e.g, a wild-type SECX and/or NOVX sequence, is hybridized to a cDNA or other DNA product from a test cell(s). The duplex is treated with a DNA mismatch repair enzyme, and the cleavage products, if any, can be detected from electrophoresis protocols or the like. See, e.g., U.S. Pat. No. 5,459,039.

In other embodiments, alterations in electrophoretic mobility will be used to identify mutations in SECX and/or NOVX genes. For example, single strand conformation polymorphism (SSCP) may be used to detect differences in electrophoretic mobility between mutant and wild type nucleic acids. See, e.g., Orita, et al., 1989. Proc. Natl. Acad. Sci. USA: 86: 2766; Cotton, 1993. Mutat. Res. 285: 125-144; Hayashi, 1992. Genet. Anal. Tech. Appl 9: 73-79. Single-stranded DNA fragments of sample and control SECX and/or NOVX nucleic acids will be denatured and allowed to renature. The secondary structure of single-stranded nucleic acids varies according to sequence, the resulting alteration in electrophoretic mobility enables the detection of even a single base change. The DNA fragments may be labeled or detected with labeled probes. The sensitivity of the assay may be enhanced by using RNA (rather than DNA), in which the secondary structure is more sensitive to a change in sequence. In one embodiment, the subject method utilizes heteroduplex analysis to separate double stranded heteroduplex molecules on the basis of changes in electrophoretic mobility. Se e g, Keen, et al., 1991. Trends Genet. 7: 5.

In yet another embodiment, the movement of mutant or wild-type fragments in polyacrylamide gels containing a gradient of denaturant is assayed using denaturing gradient gel electrophoresis (DGGE). See, e.g., Myers, et al., 1985. Nature 313: 495. When DGGE is used as the method of analysis, DNA will be modified to insure that it does not completely denature, for example by adding a GC clamp of approximately 40 bp of high-melting GC-rich DNA by PCR. In a further embodiment, a temperature gradient is used in place of a denaturing gradient to identify differences in the mobility of control and sample DNA. See, e.g., Rosenbaum and Reissner, 1987. Biophys. Chem. 265: 12753.

Examples of other techniques for detecting point mutations include, but are not limited to, selective oligonucleotide hybridization, selective amplification, or selective primer extension. For example, oligonucleotide primers may be prepared in which the known mutation is placed centrally and then hybridized to target DNA under conditions that permit hybridization only if a perfect match is found. See, e.g., Saiki, et al., 1986. Nature 324: 163; Saiki, et al., 1989. Proc. Natl. Acad. Sci. USA 86: 6230. Such allele specific oligonucleotides are hybridized to PCR amplified target DNA or a number of different mutations when the oligonucleotides are attached to the hybridizing membrane and hybridized with labeled target DNA.

Alternatively, allele specific amplification technology that depends on selective PCR amplification may be used in conjunction with the instant invention. Oligonucleotides used as primers for specific amplification may carry the mutation of interest in the center of the molecule (so that amplification depends on differential hybridization; see, e.g., Gibbs, et al., 1989. Nucl. Acids Res. 17: 2437-2448) or at the extreme 3′-terminus of one primer where, under appropriate conditions, mismatch can prevent, or reduce polymerase extension (see, e.g., Prossner, 1993. Tibtech. 11: 238). In addition it may be desirable to introduce a novel restriction site in the region of the mutation to create cleavage-based detection. See, e.g., Gasparini, et al., 1992. Mol. Cell Probes 6: 1. It is anticipated that in certain embodiments amplification may also be performed using Taq ligase for amplification. See, e.g., Barany 1991. Proc. Natl. Acad. Sci. USA 88: 189. In such cases, ligation will occur only if there is a perfect match at the 3′-terminus of the 5′ sequence, making it possible to detect the presence of a known mutation at a specific site by looking for the presence or absence of amplification.

The methods described herein may be performed, for example, by utilizing pre-packaged diagnostic kits comprising at least one probe nucleic acid or antibody reagent described herein, which may be conveniently used, e.g., in clinical settings to diagnose patients exhibiting symptoms or family history of a disease or illness involving an SECX and/or NOVX gene.

Furthermore, any cell type or tissue, preferably peripheral blood leukocytes, in which SECX and/or NOVX is expressed may be utilized in the prognostic assays described herein. However, any biological sample containing nucleated cells may be used, including, for example, buccal mucosal cells.

Pharmacogenomics

Agents, or modulators that have a stimulatory or inhibitory effect on SECX and/or NOVX activity (e.g., SECX and/or NOVX gene expression), as identified by a screening assay described herein can be administered to individuals to treat (prophylactically or therapeutically) disorders (The disorders include metabolic disorders, diabetes, obesity, infectious disease, anorexia, cancer-associated cachexia, cancer, neurodegenerative disorders, Alzheimer's Disease, Parkinson's Disorder, immune disorders, and hematopoietic disorders, and the various dyslipidemias, metabolic disturbances associated with obesity, the metabolic syndrome X and wasting disorders associated with chronic diseases and various cancers.) In conjunction with such treatment., the pharmacogenomics (i.e., the study of the relationship between an individual's genotype and that individual's response to a foreign compound or drug) of the individual may be considered. Differences in metabolism of therapeutics can lead to severe toxicity or therapeutic failure by altering the relation between dose and blood concentration of the pharmacologically active drug. Thus, the pharmacogenomics of the individual permits the selection of effective agents (e.g., drugs) for prophylactic or therapeutic treatments based on a consideration of the individual's genotype. Such pharmacogenomics can further be used to determine appropriate dosages and therapeutic regimens. Accordingly, the activity of SECX and/or NOVX protein, expression of SECX and/or NOVX nucleic acid, or mutation content of SECX and/or NOVX genes in an individual can be determined to thereby select appropriate agent(s) for therapeutic or prophylactic treatment of the individual.

Pharmacogenomics deals with clinically significant hereditary variations in the response to drugs due to altered drug disposition and abnormal action in affected persons. See e.g., Eichelbaum, 1996. Clin. Exp. Pharmacol. Physiol., 23: 983-985; Linder, 1997. Clin. Chem., 43: 254-266. In general, two types of pharmacogenetic conditions can be differentiated. Genetic conditions transmitted as a single factor altering the way drugs act on the body (altered drug action) or genetic conditions transmitted as single factors altering the way the body acts on drugs (altered drug metabolism). These pharmacogenetic conditions can occur either as rare defects or as polymorphisms. For example, glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common inherited enzymopathy in which the main clinical complication is hemolysis after ingestion of oxidant drugs (anti-malarials, sulfonamides, analgesics, nitrofurans) and consumption of fava beans.

As an illustrative embodiment, the activity of drug metabolizing enzymes is a major determinant of both the intensity and duration of drug action. The discovery of genetic polymorphisms of drug metabolizing enzymes (e.g., N-acetyltransferase 2 (NAT 2) and cytochrome PREGNANCY ZONE PROTEIN PRECURSOR enzymes CYP2D6 and CYP2C19) has provided an explanation as to why some patients do not obtain the expected drug effects or show exaggerated drug response and serious toxicity after taking the standard and safe dose of a drug. These polymorphisms are expressed in two phenotypes in the population, the extensive metabolizer (EM) and poor metabolizer (PM). The prevalence of PM is different among different populations. For example, the gene coding for CYP2D6 is highly polymorphic and several mutations have been identified in PM, which all lead to the absence of functional CYP2D6. Poor metabolizers of CYP2D6 and CYP2C19 quite frequently experience exaggerated drug response and side effects when they receive standard doses. If a metabolite is the active therapeutic moiety, PM show no therapeutic response, as demonstrated for the analgesic effect of codeine mediated by its CYP2D6-formed metabolite morphine. At the other extreme are the so called ultra-rapid metabolizers who do not respond to standard doses. Recently, the molecular basis of ultra-rapid metabolism has been identified to be due to CYP2D6 gene amplification.

Thus, the activity of SECX and/or NOVX protein, expression of SECX and/or NOVX nucleic acid, or mutation content of SECX and/or NOVX genes in an individual can be determined to thereby select appropriate agent(s) for therapeutic or prophylactic treatment of the individual. In addition, pharmacogenetic studies can be used to apply genotyping of polymorphic alleles encoding drug-metabolizing enzymes to the identification of an individual's drug responsiveness phenotype. This knowledge, when applied to dosing or drug selection, can avoid adverse reactions or therapeutic failure and thus enhance therapeutic or prophylactic efficiency when treating a subject with an SECX and/or NOVX modulator, such as a modulator identified by one of the exemplary screening assays described herein.

Monitoring of Effects During Clinical Trials

Monitoring the influence of agents (e.g., drugs, compounds) on the expression or activity of SECX and/or NOVX (e.g. the ability to modulate aberrant cell proliferation and/or differentiation) can be applied not only in basic drug screening, but also in clinical trials. For example, the effectiveness of an agent determined by a screening assay as described herein to increase SECX and/or NOVX gene expression, protein levels, or upregulate SECX and/or NOVX activity, can be monitored in clinical trails of subjects exhibiting decreased SECX and/or NOVX gene expression, protein levels, or downregulated SECX and/or NOVX activity. Alternatively, the effectiveness of an agent determined by a screening assay to decrease SECX and/or NOVX gene expression, protein levels, or downregulate SECX and/or NOVX activity, can be monitored in clinical trails of subjects exhibiting increased SECX and/or NOVX gene expression, protein levels, or upregulated SECX and/or NOVX activity. In such clinical trials, the expression or activity of SECX and/or NOVX and, preferably, other genes that have been implicated in, for example, a cellular proliferation or immnune disorder can be used as a “read out” or markers of the immune responsiveness of a particular cell.

By way of example, and not of limitation, genes, including SECX and/or NOVX, that are modulated in cells by treatment with an agent (e.g., compound, drug or small molecule) that modulates SECX and/or NOVX activity (e.g., identified in a screening assay as described herein) can be identified. Thus, to study the effect of agents on cellular proliferation disorders, for example, in a clinical trial, cells can be isolated and RNA prepared and analyzed for the levels of expression of SECX and/or NOVX and other genes implicated in the disorder. The levels of gene expression (i.e., a gene expression pattern) can be quantified by Northern blot analysis or RT-PCR, as described herein, or alternatively by measuring the amount of protein produced, by one of the methods as described herein, or by measuring the levels of activity of SECX and/or NOVX or other genes. In this manner, the gene expression pattern can serve as a marker, indicative of the physiological response of the cells to the agent. Accordingly, this response state may be determined before, and at various points during, treatment of the individual with the agent.

In one embodiment, the invention provides a method for monitoring the effectiveness of treatment of a subject with an agent (e g, an agonist, antagonist, protein, peptide, peptidomimetic, nucleic acid, small molecule, or other drug candidate identified by the screening assays described herein) comprising the steps of (i) obtaining a pre-administration sample from a subject prior to administration of the agent; (ii) detecting the level of expression of an SECX and/or NOVX protein, mRNA, or genomic DNA in the preadministration sample; (iii) obtaining one or more post-administration samples from the subject; (iv) detecting the level of expression or activity of the SECX and/or NOVX protein, mRNA, or genomic DNA in the post-administration samples; (v) comparing the level of expression or activity of the SECX and/or NOVX protein, mRNA, or genomic DNA in the pre-administration sample with the SECX and/or NOVX protein, mRNA, or genomic DNA in the post administration sample or samples; and (vi) altering the administration of the agent to the subject accordingly. For example, increased administration of the agent may be desirable to increase the expression or activity of SECX and/or NOVX to higher levels than detected, i.e., to increase the effectiveness of the agent. Alternatively, decreased administration of the agent may be desirable to decrease expression or activity of SECX and/or NOVX to lower levels than detected, i.e., to decrease the effectiveness of the agent.

Methods of Treatment

The invention provides for both prophylactic and therapeutic methods of treating a subject at risk of (or susceptible to) a disorder or having a disorder associated with aberrant SECX and/or NOVX expression or activity. The disorders include cardiomyopathy, atherosclerosis, hypertension, congenital heart defects, aortic stenosis, atrial septal defect (ASD), atrioventricular (A-V) canal defect, ductus arteriosus, pulmonary stenosis, subaortic stenosis, ventricular septal defect (VSD), valve diseases, tuberous sclerosis, scleroderma, obesity, transplantation, adrenoleukodystrophy, congenital adrenal hyperplasia, prostate cancer, neoplasm; adenocarcinoina, lymphoma, uterus cancer, fertility, hemophilia, hypercoagulation, idiopathic thrombocytopenic purpura, immnunodeficiencies, graft versus host disease, AIDS, bronchial asthma, Crohn's disease; multiple sclerosis, treatment of Albright Hereditary Ostoeodystrophy, and other diseases, disorders and conditions of the like.

These methods of treatment will be discussed more fully, below.

Disease and Disorders

Diseases and disorders that are characterized by increased (relative to a subject not suffering from the disease or disorder) levels or biological activity may be treated with Therapeutics that antagonize (i.e., reduce or inhibit) activity. Therapeutics that antagonize activity may be administered in a therapeutic or prophylactic manner. Therapeutics that may be utilized include, but are not limited to: (i) an aforementioned peptide, or analogs, derivatives, fragments or homologs thereof, (ii) antibodies to an aforementioned peptide; (iii) nucleic acids encoding an aforementioned peptide; (iv) administration of antisense nucleic acid and nucleic acids that are “dysfunctional” (i e, due to a heterologous insertion within the coding sequences of coding sequences to an aforementioned peptide) that are utilized to “knockout” endogenous function of an aforementioned peptide by homologous recombination (see, e.g., Capecchi, 1989. Science 244: 1288-1292); or (v) modulators (i.e., inhibitors, agonists and antagonists, including additional peptide mimetic of the invention or antibodies specific to a peptide of the invention) that alter the interaction between an aforementioned peptide and its binding partner.

Diseases and disorders that are characterized by decreased (relative to a subject not suffering from the disease or disorder) levels or biological activity may be treated with Therapeutics that increase (i.e., are agonists to) activity. Therapeutics that upregulate activity may be administered in a therapeutic or prophylactic manner. Therapeutics that may be utilized include, but are not limited to, an aforementioned peptide, or analogs, derivatives, fragments or homologs thereof; or an agonist that increases bioavailability.

Increased or decreased levels can be readily detected by quantifying peptide and/or RNA, by obtaining a patient tissue sample (e.g., from biopsy tissue) and assaying it in vitro for RNA or peptide levels, structure and/or activity of the expressed peptides (or mRNAs of an aforementioned peptide). Methods that are well-known within the art include, but are not limited to, inmmunoassays (e.g., by Western blot analysis, immunoprecipitation followed by sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis, immunocytochemistry, etc.) and/or hybridization assays to detect expression of mRNAs (e.g., Northern assays, dot blots, in situ hybridization, and the like).

Prophylactic Methods

In one aspect, the invention provides a method for preventing, in a subject, a disease or condition associated with an aberrant SECX and/or NOVX expression or activity, by administering to the subject an agent that modulates SECX and/or NOVX expression or at least one SECX and/or NOVX activity. Subjects at risk for a disease that is caused or contributed to by aberrant SECX and/or NOVX expression or activity can be identified by, for example, any or a combination of diagnostic or prognostic assays as described herein. Administration of a prophylactic agent can occur prior to the manifestation of symptoms characteristic of the SECX and/Dr NOVX aberrancy, such that a disease or disorder is prevented or, alternatively, delayed in its progression. Depending upon the type of SECX and/or NOVX aberrancy, for example, an SECX and/or NOVX agonist or SECX and/or NOVX antagonist agent can be used for treating the subject. The appropriate agent can be determined based on screening assays described herein. The prophylactic methods of the invention are further discussed in the following subsections.

Therapeutic Methods

Another aspect of the invention pertains to methods of modulating SECX and/or NOVX expression or activity for therapeutic purposes. The modulatory method of the invention involves contacting a cell with an agent that modulates one or more of the activities of SECX and/or NOVX protein activity associated with the cell. An agent that modulates SECX and/or NOVX protein activity can be an agent as described herein, such as a nucleic acid or a protein, a naturally-occurring cognate ligand of an SECX and/or NOVX protein, a peptide, an SECX and/or NOVX peptidomimetic, or other small molecule. In one embodiment, the agent stimulates one or more SECX and/or NOVX protein activity. Examples of such stimulatory agents include active SECX and/or NOVX protein and a nucleic acid molecule encoding SECX and/or NOVX that has been introduced into the cell. In another embodiment, the agent inhibits one or more SECX and/or NOVX protein activity. Examples of such inhibitory agents include antisense SECX and/or NOVX nucleic acid molecules and anti-SECX and/or NOVX antibodies. These modulatory methods can be performed in vitro (e.g., by culturing the cell with the agent) or, alternatively, in vivo (e.g., by administering the agent to a subject). As such, the invention provides methods of treating an individual afflicted with a disease or disorder characterized by aberrant expression or activity of an SECX and/or NOVX protein or nucleic acid molecule. In one embodiment, the method involves administering an agent (e.g., an agent identified by a screening assay described herein), or combination of agents that modulates (e.g., up-regulates or down-regulates) SECX and/or NOVX expression or activity. In another embodiment, the method involves administering an SECX and/or NOVX protein or nucleic acid molecule as therapy to compensate for reduced or aberrant SECX and/or NOVX expression or activity.

Stimulation of SECX and/or NOVX activity is desirable in situations in which SECX and/or NOVX is abnormally downregulated and/or in which increased SECX and/or NOVX activity is likely to have a beneficial effect. One example of such a situation is where a subject has a disorder characterized by aberrant cell proliferation and/or differentiation (e g. cancer or immune associated disorders). Another example of such a situation is where the subject has a gestational disease (e.g, preclampsia).

Determination of the Biological Effect of the Therapeutic

In various embodiments of the invention, suitable in vitro or in vivo assays are performed to determine the effect of a specific Therapeutic and whether its administration is indicated for treatment of the affected tissue.

In various specific embodiments, in vitro assays may be performed with representative cells of the type(s) involved in the patient's disorder, to determine if a given Therapeutic exerts the desired effect upon the cell type(s). Compounds for use in therapy may be tested in suitable animal model systems including, but not limited to rats, mice, chicken, cows, monkeys, rabbits, and the like, prior to testing in human subjects. Similarly, for in vivo testing, any of the animal model system known in the art may be used prior to administration to human subjects.

Prophylactic and Therapeutic Uses of the Compositions of the Invention

The SECX and/or NOVX nucleic acids and proteins of the invention are useful in potential prophylactic and therapeutic applications implicated in a variety of disorders including, but not limited to: metabolic disorders, diabetes, obesity, infectious disease, anorexia, cancer-associated cancer, neurodegenerative disorders, Alzheimer's Disease, Parkinson's Disorder, immune disorders, hematopoietic disorders, and the various dyslipidemias, metabolic disturbances associated with obesity, the metabolic syndrome X and wasting disorders associated with chronic diseases and various cancers.

As an example, a cDNA encoding the SECX and/or NOVX protein of the invention may be useful in gene therapy, and the protein may be useful when administered to a subject in need thereof. By way of non-limiting example, the compositions of the invention will have efficacy for treatment of patients suffering from: metabolic disorders, diabetes, obesity, infectious disease, anorexia, cancer-associated cachexia, cancer, neurodegenerative disorders, Alzheimer's Disease, Parkinson's Disorder, immune disorders, hematopoietic disorders, and the various dyslipidemias.

Both the novel nucleic acid encoding the SECX and/or NOVX protein, and the SECX and/or NOVX protein of the invention, or fragments thereof, may also be useful in diagnostic applications, wherein the presence or amount of the nucleic acid or the protein are to be assessed. A further use could be as an anti-bacterial molecule (i.e., some peptides have been found to possess anti-bacterial properties). These materials are further useful in the generation of antibodies, which immunospecifically-bind to the novel substances of the invention for use in therapeutic or diagnostic methods.

The invention will be further described in the following examples, which do not limit the scope of the invention described in the claims.

EXAMPLES Example 1 Identification of SECX and/or NOVX Clones

The novel SECX and/or NOVX target sequences identified in the present invention were subjected to the exon linking process to confirm the sequence. PCR primers were designed by starting at the most upstream sequence available, for the forward primer, and at the most downstream sequence available for the reverse primer. Table 15A shows the sequences of the PCR primers used for obtaining different clones. In each case, the sequence was examined, walking inward from the respective termini toward the coding sequence, until a suitable sequence that is either unique or highly selective was encountered, or, in the case of the reverse primer, until the stop codon was reached. Such primers were designed based on in silico predictions for the full length cDNA, part (one or more exons) of the DNA or protein sequence of the target sequence, or by translated homology of the predicted exons to closely related human sequences from other species. These primers were then employed in PCR amplification based on the following pool of human cDNAs: adrenal gland, bone marrow, brain—amygdala, brain—cerebellum, brain—hippocampus, brain—substantia nigra, brain—thalamus, brain—whole, fetal brain, fetal kidney, fetal liver, fetal lung, heart, kidney, lymphoma—Raji, mammary gland, pancreas, pituitary gland, placenta, prostate, salivary gland, skeletal muscle, small intestine, spinal cord, spleen, stomach, testis, thyroid, trachea, uterus. Usually the resulting amplicons were gel purified, cloned and sequenced to high redundancy. The PCR product derived from exon linking was cloned into the pCR2.1 vector from Invitrogen. The resulting bacterial clone has an insert covering the entire open reading frame cloned into the pCR2.1 vector. The resulting sequences from all clones were assembled with themselves, with other fragments in CuraGen Corporation's database and with public ESTs. Fragments and ESTs were included as components for an assembly when the extent of their identity with another component of the assembly was at least 95% over 50 bp. In addition, sequence traces were evaluated manually and edited for corrections if appropriate. These procedures provide the sequence reported herein.

Physical clone: Exons were predicted by homology and the intron/exon boundaries were determined using standard genetic rules. Exons were further selected and refined by means of similarity determination using multiple BLAST (for example, tBlastN, BlastX, and BlastN) searches, and, in some instances, GeneScan and Grail. Expressed sequences from both public and proprietary databases were also added when available to further define and complete the gene sequence. The DNA sequence was then manually corrected for apparent inconsistencies thereby obtaining the sequences encoding the full-length protein.

The quantitative expression of various clones was assessed using microtiter plates containing RNA samples from a variety of normal and pathology-derived cells, cell lines and tissues using real time quantitative PCR (RTQ PCR). RTQ PCR was performed on an Applied Biosystems ABI PRISM® 7700 or an ABI PRISM® 7900 HT Sequence Detection System. Various collections of samples are assembled on the plates, and referred to as Panel 1 (containing normal tissues and cancer cell lines), Panel 2 (containing samples derived from tissues from normal and cancer sources), Panel 3 (containing cancer cell lines), Panel 4 (containing cells and cell lines from normal tissues and cells related to inflammatory conditions), Panel 5D/5I (containing human tissues and cell lines with an emphasis on metabolic diseases), AI_comprehensive_panel (containing normal tissue and samples from autoimmune diseases), Panel CNSD.01 (containing central nervous system samples from normal and diseased brains) and CNS_neurodegeneration_panel (containing samples from normal and Alzheimer's diseased brains).

RNA integrity from all samples is controlled for quality by visual assessment of agarose gel electropherograms using 28S and 18S ribosomal RNA staining intensity ratio as a guide (2:1 to 2.5:1 28s:18s) and the absence of low molecular weight RNAs that would be indicative of degradation products. Samples are controlled against genomic DNA contamination by RTQ PCR reactions run in the absence of reverse transcriptase using probe and primer sets designed to amplify across the span of a single exon.

First, the RNA samples were normalized to reference nucleic acids such as constitutively expressed genes (for example, β-actin and GAPDH). Normalized RNA (5 ul) was converted to cDNA and analyzed by RTQ-PCR using One Step RT-PCR Master Mix Reagents (Applied Biosystems. Catalog No. 4309169) and gene-specific primers according to the manufacturer's instructions.

In other cases, non-nomnalized RNA samples were converted to single strand cDNA (sscDNA) using Superscript II (Invitrogen Corporation; Catalog No. 18064-147) and random hexamers according to the manufacturer's instructions. Reactions containing up to 10 μg of total RNA were performed in a volume of 20 μl and incubated for 60 minutes at 42° C. This reaction can be scaled up to 50 μg of total RNA in a final volume of 100 μl. sscDNA samples are then normalized to reference nucleic acids as described previously, using 1×TaqMan® Universal Master mix (Applied Biosystems; catalog No. 4324020), following the manufacturer's instructions.

Probes and primers were designed for each assay according to Applied Biosystems Primer Express Software package (version 1 for Apple Computer's Macintosh Power PC) or a similar algorithm using the target sequence as input. Default settings were used for reaction conditions and the following parameters were set before selecting primers: primer concentration=250 nM, primer melting temperature (Tm) range=58°-60° C., primer optimal Tm=59° C., maximum primer difference=2° C., probe does not have 5′G, probe Tm must be 10° C. greater than primer Tm, amnplicon size 75 bp to 100 bp. The probes and primers selected (see below) were synthesized by Synthegen (Houston, Tex., USA). Probes were double purified by HPLC to remove uncoupled dye and evaluated by mass spectroscopy to verify coupling of reporter and quencher dyes to the 5′ and 3′ ends of the probe, respectively. Their final concentrations were: forward and reverse primers, 900 nM each, and probe, 200 nM.

PCR conditions: When working with RNA samples, normalized RNA from each tissue and each cell line was spotted in each well of either a 96 well or a 384-well PCR plate (Applied Biosystems). PCR cocktails included either a single gene specific probe and primers set, or two multiplexed probe and primers sets (a set specific for the target clone and another gene-specific set multiplexed with the target probe). PCR reactions were set up using TaqMan® One-Step RT-PCR Master Mix (Applied Biosystems, Catalog No. 4313803) following manufacturer's instructions. Reverse transcription was performed at 48° C. for 30 minutes followed by amplification/PCR cycles as follows: 95° C. 10 min, then 40 cycles of 95° C. for 15 seconds, 60° C. for 1 minute. Results were recorded as CT values (cycle at which a given sample crosses a threshold level of fluorescence) using a log scale, with the difference in RNA concentration between a given sample and the sample with the lowest CT value being represented as 2 to the power of delta CT. The percent relative expression is then obtained by taking the reciprocal of this RN A difference and multiplying by 100.

When working with sscDNA samples, normalized sscDNA was used as described previously for RNA samples. PCR reactions containing one or two sets of probe and primers were set up as described previously using 1×TaqMan® Universal Master mix (Applied Biosystems; catalog No. 4324020), following the manufacturer's instructions. PCR amplification was performed as follows: 95° C. 10 min, then 40 cycles of 95° C. for 15 seconds, 60° C. for 1 minute. Results were analyzed and processed as described previously.

Panels 2D and 2.2

The plates for Panels 2D and 2.2 generally include 2 control wells and 94 test samples composed of RNA or cDNA isolated from human tissue procured by surgeons working in close cooperation with the National Cancer Institute's Cooperative Human Tissue Network (CHTN) or the National Disease Research Initiative (NDRI). The tissues are derived from human malignancies and in cases where indicated many malignant tissues have “matched margins” obtained from noncancerous tissue just adjacent to the tumor. These are termed normal adjacent tissues and are denoted “NAT” in the results below. The tumor tissue and the “matched margins” are evaluated by two independent pathologists (the surgical pathologists and again by a pathologist at NDRI or CHTN). This analysis provides a gross histopathological assessment of tumor differentiation grade. Moreover, most samples include the original surgical pathology report that provides information regarding the clinical stage of the patient. These matched margins are taken from the tissue surrounding (i.e. immediately proximal) to the zone of surgery (designated “NAT”, for normal adjacent tissue, in Table RR). In addition, RNA and cDNA samples were obtained from various human tissues derived from autopsies performed on elderly people or sudden death victims (accidents, etc.). These tissues were ascertained to be free of disease and were purchased from various commercial sources such as Clontech (Palo Alto, Calif.), Research Genetics, and Invitrogen

Panel 3D

The plates of Panel 3D are comprised of 94 cDNA samples and two control samples. Specifically, 92 of these samples ire derived from cultured human cancer cell lines, 2 samples of human primary cerebellar tissue and 2 controls. The human cell lines are generally obtained from ATCC (American Type Culture Collection), NCI or the German tumor cell bank and fall into the following tissue groups: Squamous cell carcinoma of the tongue, breast cancer, prostate cancer, melanoma, epidermoid carcinoma, sarcomas, bladder carcinomas, pancreatic cancers, kidney cancers, leukemias/lymphomas, ovarian/uterine/cervical, gastric, colon, lung and CNS cancer cell lines. In addition, there are two independent samples of cerebellum. These cells are all cultured under standard recommended conditions and RNA extracted using the standard procedures. The cell lines in panel 3D and 1.3D are of the most common cell lines used in the scientific literature.

Panels 4D, 4R, and 4.1D

Panel 4 includes samples on a 96 well plate (2 control wells, 94 test samples) composed of RNA (Panel 4R) or cDNA (Panels 4D/4.1D) isolated from various human cell lines or tissues related to inflammatory conditions. Total RNA from control normal tissues such as colon and lung (Stratagene, La Jolla, Calif.) and thymus and kidney (Clontech) was employed. Total RNA from liver tissue from cirrhosis patients and kidney from lupus patients was obtained from BioChain (Biochain Institute, Inc., Hayward, Calif.). Intestinal tissue for RNA preparation from patients diagnosed as having Crohn's disease and ulcerative colitis was obtained from the National Disease Research Interchange (NDRI) (Philadelphia, Pa.).

Astrocytes, lung fibroblasts, dermal fibroblasts, coronary artery smooth muscle cells, small airway epithelium, bronchial epithelium, microvascular dermal endothelial cells, microvascular lung endothelial cells, human pulmonary aortic endothelial cells, human umbilical vein endothelial cells were all purchased from Clonetics (Walkersville, Md.) and grown in the media supplied for these cell types by Clonetics. These primary cell types were activated with various cytokines or combinations of cytokines for 6 and/or 12-14 hours, as indicated. The following cytokines were used; IL-1 beta at approximately 1-5 ng/ml, TNF alpha at approximately 5-10 ng/ml, IFN gamma at approximately 20-50 ng/ml, IL-4 at approximately 5-10 ng/ml, IL-9 at approximately 5-10 ng/ml, IL-13 at approximately 5-10 ng/ml. Endothelial cells were sometimes starved for various times by culture in the basal media from Clonetics with 0.1% serum.

Mononuclear cells were prepared from blood of employees at CuraGen Corporation, using Ficoll LAK cells were prepared from these cells by culture in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco/Life Technologies, Rockville, Md.), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵M (Gibco), and 10 mM Hepes (Gibco) and Interleukin 2 for 4-6 days. Cells were then either activated with 10-20 ng/ml PMA and 1-2 μg/ml ionomycin, IL-12 at 5-10 ng/ml, IFN gamma at 20-50 ng/ml and IL-18 at 5-10 ng/ml for 6 hours. In some cases, mononuclear cells were cultured for 4-5 days in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵M (Gibco), and 10 mM Hepes (Gibco) with PHA (phytohemagglutinin) or PWM (pokeweed mitogen) at approximately 5 μg/ml. Samples were taken at 24, 48 and 72 hours for RNA preparation. MLR (mixed lymphocyte reaction) samples were obtained by taking blood from two donors, isolating the mononuclear cells using Ficoll and mixing the isolated mononuclear cells 1:1 at a final concentration of approximately 2×10⁶ cells/ml in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol (5.5×10⁻⁵M) (Gibco), and 10 mM Hepes (Gibco). The MLR was cultured and samples taken at various time points ranging from 1-7 days for RNA preparation.

Monocytes were isolated from mononuclear cells using CD14 Miltenyi Beads, +ve VS selection columns and a Vario Magnet according to the manufacturer's instructions. Monocytes were differentiated into dendritic cells by culture in DMEM 5% fetal calf serum (FCS) (Hyclone, Logan, Utah), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanlol 5.5×10⁻⁵ M (Gibco), and 10 mM Hepes (Gibco), 50 ng/ml GMCSF and 5 ng/ml IL-4 for 5-7 days. Macrophages were prepared by culture of monocytes for 5-7 days in DMEM 5% FCS (Hyclone). 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵M (Gibco), 10 mM Hepes (Gibco) and 10% AB Human Serum or MCSF at approximately 50 ng/ml. Monocytes, macrophages and dendritic cells were stimulated for 6 and 12-14 hours with lipopolysaccharide (LPS) at 100 ng/ml. Dendritic cells were also stimulated with anti-CD40 monoclonal antibody (Pharmingen) at 10 μg/ml for 6 and 12-14 hours.

CD4 lymphocytes, CD8 lymphocytes and NK cells were also isolated from mononuclear cells using CD4, CD8 and CD56 Miltenyi beads, positive VS selection columns and a Vario Magnet according to the manufacturer's instructions. CD45RA and CD45RO CD4 lymphocytes were isolated by depleting mononuclear cells of CD8, CD56, CD14 and CD19 cells using CD8, CD56, CD14 and CD19 Miltenyi beads and positive selection. CD45RO beads were then used to isolate the CD45RO CD4 lymphocytes with the remaining cells being CD45RA CD4 lymphocytes. CD45RA CD4, CD45RO CD4 and CD8 lymphocytes were placed in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵M (Gibco), and 10 mM Hepes (Gibco) and plated at 10⁶ cells/ml onto Falcon 6 well tissue culture plates that had been coated overnight with 0.5 μg/ml anti-CD28 (Pharmingen) and 3 ug/ml anti-CD3 (OKT3, ATCC) in PBS. After 6 and 24 hours, the cells were harvested for RNA preparation. To prepare chronically activated CD8 lymphocytes, we activated the isolated CD8 lymphocytes for 4 days on anti-CD28 and anti-CD3 coated plates and then harvested the cells and expanded them in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵M (Gibco), and 10 mM Hepes (Gibco) and IL-2. The expanded CD8 cells were then activated again with plate bound anti-CD3 and anti-CD28 for 4 days and expanded as before. RNA was isolated 6 and 24 hours after the second activation and after 4 days of the second expansion culture. The isolated NK cells were cultured in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵M (Gibco), and 10 mM Hepes (Gibco) and IL-2 for 4-6 days before RNA was prepared.

To obtain B cells, tonsils were procured from NDRI. The tonsil was cut up with sterile dissecting scissors and then passed through a sieve. Tonsil cells were then spun down and resupended at 10⁶ cells/ml in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵M (Gibco), and 10 mM Hepes (Gibco). To activate the cells, we used PWM at 5 μg/ml or anti-CD40 (Pharmingen) at approximately 10 μg/ml and IL-4 at 5-10 ng/ml. Cells were harvested for RNA preparation at 24, 48 and 72 hours.

To prepare the primary and secondary Th1/Th2 and Tr1 cells, six-well Falcon plates were coated overnight with 10 μg/ml anti-CD28 (Pharmingen) and 2 μg/ml OKT3 (ATCC), and then washed twice with PBS. Umbilical cord blood CD4 lymphocytes (Poietic Systems, German Town, Md.) were cultured at 10⁵-10⁶ cells/ml in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵ M (Gibco), 10 mM Hepes (Gibco) and IL-2 (4 ng/ml). IL-12 (5 ng/ml) and anti-IL4 (1 μg/ml) were used to direct to Th1, while IL-4 (5 ng/ml) and anti-IFN gamma (1 μg/ml) were used to direct to Th2 and IL-10 at 5 ng/ml was used to direct to Tr1. After 4-5 days, the activated Th1, Th2 and Tr1 lymphocytes were washed once in DMEM and expanded for 4-7 days in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵M (Gibco), 10 mM Hepes (Gibco) and IL-2 (1 ng/ml). Following this, the activated Th1, Th2 and Tr1 lymphocytes were re-stimulated for 5 days with anti-CD28/OKT3 and cytokines as described above, but with the addition of anti-CD95L (1 μg/ml) to prevent apoptosis. After 4-5 days, the Th1, Th2 and Tr1 lymphocytes were washed and then expanded again with IL-2 for 4-7 days. Activated Th1 and Th2 lymphocytes were maintained in this way for a maximum of three cycles. RNA was prepared from primary and secondary Th1, Th2 and Tr1 after 6 and 24 hours following the second and third activations with plate bound anti-CD3 and anti-CD28 mAbs and 4 days into the second and third expansion cultures in Interleukin 2.

The following leukocyte cells lines were obtained from the ATCC: Ramos, EOL-1, KU-812. EOL cells were further differentiated by culture in 0.1 mM dbcAMP at 5×10⁵ cells/ml for 8 days, changing the media every 3 days and adjusting the cell concentration to 5×10⁵ cells/ml. For the culture of these cells, we used DMEM or RPMI (as recommended by the ATCC), with the addition of 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵ M (Gibco), 10 mM Hepes (Gibco). RNA was either prepared from resting cells or cells activated with PMA at 10 ng/ml and ionomycin at 1 ug/ml for 6 and 14 hours. Keratinocyte line CCD106 and an airway epithelial tumor line NCI-H292 were also obtained from the ATCC. Both were cultured in DMEM 5% FCS (Hyclone), 100 μM non essential amino acids (Gibco), 1 mM sodium pyruvate (Gibco), mercaptoethanol 5.5×10⁻⁵ M (Gibco), and 10 mM Hepes (Gibco). CCD1106 cells were activated for 6 and 14 hours with approximately 5 ng/ml TNF alpha and 1 ng/ml IL-1 beta, while NCI-H292 cells were activated for 6 and 14 hours with the following cytokines: 5 ng/ml L-4, 5 ng/ml IL-9, 5 ng/ml IL-13 and 25 ng/ml IFN gamma.

For these cell lines and blood cells, RNA was prepared by lysing approximately 10⁷ cells/ml using Trizol (Gibco BRL). Briefly, 1/10 volume of bromochloropropane (Molecular Research Corporation) was added to the RNA sample, vortexed and after 10 minutes at room temperature, the tubes were spun at 14,000 rpm in a Sorvall SS34 rotor. The aqueous phase was removed and placed in a 15 ml Falcon Tube. An equal volume of isopropanol was added and left at −20° C. overnight. The precipitated RNA was spun down at 9,000 rpm for 15 min in a Sorvall SS34 rotor and washed in 70% ethanol. The pellet was redissolved in 300 μl of RNAse-free water and 35 μl buffer (Promega) 5 μl DTT 7 μl RNAsin and 8 μl DNAse were added. The tube was incubated at 37° C. for 30 minutes to remove contaminating genomic DNA, extracted once with phenol chloroform and re-precipitated with 1/10 volume of 3M sodium acetate and 2 volumes of 100% ethanol. The RNA was spun down and placed in RNAse free water. RNA was stored at −80° C.

AI_comprehensive panel_v1.0

The plates for AI_comprehensive panel_v1.0 include two control wells and 89 test samples comprised of cDNA isolated from surgical and postmortem human tissues obtained from the Backus Hospital and Clinomics (Frederick, Md.). Total RNA was extracted from tissue samples from the Backus Hospital in the Facility at CuraGen. Total RNA from other tissues was obtained from Clinomics.

Joint tissues including synovial fluid, synovium, bone and cartilage were obtained from patients undergoing total knee or hip replacement surgery at the Backus Hospital. Tissue samples were immediately snap frozen in liquid nitrogen to ensure that isolated RNA was of optimal quality and not degraded. Additional samples of osteoarthritis and rheumatoid arthritis joint tissues were obtained from Clinomics. Normal control tissues were supplied by Clinomics and were obtained during autopsy of trauma victims.

Surgical specimens of psoriatic tissues and adjacent matched tissues were provided as total RNA by Clinomics. Two male and two female patients were selected between the ages of 25 and 47. None of the patients were taking prescription drugs at the time samples were isolated.

Surgical specimens of diseased colon from patients with ulcerative colitis and Crohns disease and adjacent matched tissues were obtained from Clinomics. Bowel tissue from three female and three male Crohn's patients between the ages of 41-69 were used. Two patients were not on prescription medication while the others were taking dexamethasone, phenobarbital, or tylenol. Ulcerative colitis tissue was from three male and four female patients. Four of the patients were taking lebvid and two were on phenobarbital.

Total RNA from post mortem lung tissue from trauma victims with no disease or with emphysema, asthma or COPD was purchased from Clinomics. Emphysema patients ranged in age from 40-70 and all were smokers, this age range was chosen to focus on patients with cigarette-linked emphysema and to avoid those patients with alpha-lanti-trypsin deficiencies. Asthma patients ranged in age from 36-75, and excluded smokers to prevent those patients that could also have COPD. COPD patients ranged in age from 35-80 and included both smokers and non-smokers. Most patients were taking corticosteroids, and bronchodilators.

In the labels employed to identify tissues in the AI_comprehensive panel_v1.0 panel, the following abbreviations are used:

Panels 5D and 5I

The plates for Panel 5D and 5I include two control wells and a variety of cDNAs isolated from human tissues and cell lines with an emphasis on metabolic diseases. Metabolic tissues were obtained from patients enrolled in the Gestational Diabetes study. Cells were obtained during different stages in the differentiation of adipocytes from human mesenchymal stem cells. Human pancreatic islets were also obtained.

In the Gestational Diabetes study subjects are young (18-40 years), otherwise healthy women with and without gestational diabetes undergoing routine (elective) Caesarean section. After delivery of the infant, when the surgical incisions were being repaired/closed, the obstetrician removed a small sample (<1 cc) of the exposed metabolic tissues during the closure of each surgical level. The biopsy material was rinsed in sterile saline, blotted and fast frozen within 5 minutes from the time of removal. The tissue was then flash frozen in liquid nitrogen and stored, individually, in sterile screw-top tubes and kept on dry ice for shipment to or to be picked up by CuraGen. The metabolic tissues of interest include uterine wall (smooth muscle), visceral adipose, skeletal muscle (rectus) and subcutaneous adipose. Patient descriptions are as follows:

Patient 2 Diabetic Hispanic. overweight, not on insulin Patient 7-9 Nondiabetic Caucasian and obese (BMI > 30) Patient 10 Diabetic Hispanic, overweight, on insulin Patient 11 Nondiabetic African American and overweight Patient 12 Diabetic Hispanic on insulin

Adipocyte differentiation was induced in donor progenitor cells obtained from Osirus (a division of Clonetics/Bio Whittaker) in triplicate, except for Donor 3U which had only two replicates. Scientists at Clonetics isolated, grew and differentiated human mesenchymal stem cells (HuMSCs) for CuraGen based on the published protocol found in Mark F. Pittenger, et al., Multilineage Potential of Adult Human Mesenchymal Stem Cells Science Apr. 2, 1999: 143-147. Clonetics provided Trizol lysates or frozen pellets suitable for mRNA isolation and ds cDNA production. A general description of each donor is as follows:

-   -   Donor 2 and 3 U: Mesenchymal Stem cells, Undifferentiated         Adipose     -   Donor 2 and 3 AM: Adipose, AdiposeMidway Differentiated     -   Donor 2 and 3 AD: Adipose, Adipose Differentiated

Human cell lines were generally obtained from ATCC (American Type Culture Collection), NCI or the German tumor cell bank and fall into the following tissue groups: kidney proximal convoluted tubule, uterine smooth muscle cells, small intestine, liver HepG2 cancer cells, heart primary stromal cells, and adrenal cortical adenoma cells. These cells are all cultured under standard recommended conditions and RNA extracted using the standard procedures. All samples were processed at CuraGen to produce single stranded cDNA.

Panel 5I contains all samples previously described with the addition of pancreatic islets from a 58 year old female patient obtained from the Diabetes Research Institute at the University of Miami School of Medicine. Islet tissue was processed to total RNA at an outside source and delivered to CuraGen for addition to panel 5I.

In the labels employed to identify tissues in the 5D and 5I panels, the following abbreviations are used:

-   -   GO Adipose=Greater Omentum Adipose     -   SK=Skeletal Muscle     -   UT=Uterus     -   PL=Placenta     -   AD=Adipose Differentiated     -   AM=Adipose Midway Differentiated     -   U=Undifferentiated Stem Cells

Panel CNSD.01

The plates for Panel CNSD.01 include two control wells and 94 test samples comprised of cDNA isolated from postmortem human brain tissue obtained from the Harvard Brain Tissue Resource Center. Brains are removed from calvaria of donors between 4 and 24 hours after death, sectioned by neuroanatomists, and frozen at −80° C. in liquid nitrogen vapor. All brains are sectioned and examined by neuropathologists to confirm diagnoses with clear associated neuropathology.

Disease diagnoses are taken from patient records. The panel contains two brains from each of the following diagnoses: Alzheimer's disease, Parkinson's disease, Huntington's disease, Progressive Supernuclear Palsy, Depression, and “Normal controls”. Within each of these brains, the following regions are represented: cingulate gyrus, temporal pole, globus palladus, substantia nigra, Brodman Area 4 (primary motor strip), Brodman Area 7 (parietal cortex), Brodman Area 9 (prefrontal cortex), and Brodman area 17 (occipital cortex). Not all brain regions are represented in all cases; e.g., Huntington's disease is characterized in part by neurodegeneration in the globus palladus, thus this region is impossible to obtain from confirmed Huntington's cases. Likewise Parkinson's disease is characterized by degeneration of the substantia nigra making this region more difficult to obtain. Normal control brains were examined for neuropathology and found to be free of any pathology consistent with neurodegeneration.

In the labels employed to identify tissues in the CNS panel, the following abbreviations are used:

-   -   PSP=Progressive supranuclear palsy     -   Sub Nigra=Substantia nigra     -   Glob Palladus=Globus palladus     -   Temp Pole=Temporal pole     -   Cing Gyr=Cingulate gyrus     -   BA 4=Brodman Area 4

Panel CNS_Neurodegeneration_V1.0

The plates for Panel CNS_Neurodegeneration_V1.0 include two control wells and 47 test samples comprised of cDNA isolated from postmortem human brain tissue obtained from the Harvard Brain Tissue Resource Center (McLean Hospital) and the Human Brain and Spinal Fluid Resource Center (VA Greater Los Angeles Healthcare System). Brains are removed from calvaria of donors between 4 and 24 hours after death, sectioned by neuroanatomists, and frozen at −80° C. in liquid nitrogen vapor. All brains are sectioned and examined by neuropathologists to confirm diagnoses with clear associated neuropathology.

Disease diagnoses are taken from patient records. The panel contains six brains from Alzheimer's disease (AD) patients, and eight brains from “Normal controls” who showed no evidence of dementia prior to death. The eight normal control brains are divided into two categories: Controls with no dementia and no Alzheimer's like pathology (Controls) and controls with no dementia but evidence of severe Alzheimer's like pathology, (specifically senile plaque load rated as level 3 on a scale of 0-3; 0=no evidence of plaques, 3=severe AD senile plaque load). Within each of these brains, the following regions are represented: hippocampus, temporal cortex (Brodman Area 21), parietal cortex (Brodman area 7), and occipital cortex (Brodman area 17). These regions were chosen to encompass all levels of neurodegeneration in AD. The hippocampus is a region of early and severe neuronal loss in AD; the temporal cortex is known to show neurodegeneration in AD after the hippocampus; the parietal cortex shows moderate neuronal death in the late stages of the disease; the occipital cortex is spared in AD and therefore acts as a “control” region within AD patients. Not all brain regions are represented in all cases.

In the labels employed to identify tissues in the CNS_Neurodegeneration_V1.0 panel, the following abbreviations are used:

-   -   AD Alzheimer's disease brain; patient was demented and showed         AD-like pathology upon autopsy     -   Control=Control brains:, patient not demented, showing no         neuropathology     -   Control (Path)=Control brains; patient not demented but showing         sever AD-like pathology     -   Sup Temporal Ctx=Superior Temporal Cortex     -   Inf Temporal Ctx=Inferior Temporal Cortex

AI_comprehensive panel_v1.0 Summary: Ag2255 Two experiments with the same probe and primer set both show highest expression of the CG50379-01 gene, a Frizzled-10 homolog, in samples from a subset of emphysema patients (CTs=31-32). In addition, this gene is also expressed at moderate levels in samples from the mucoepidermoid pulmonary epithelial cell line NCI-H292 activated with IL-4 or IL-13 in culture. Based on this expression profile, small molecule drugs or antibodies that antagonize the action of the putative 7-transmembrane receptor encoded by the CG50379-01 gene may be useful as therapeutics which reduce or eliminate the symptoms in patients with allergy, asthma, or chronic obstructive pulmonary diseases.

Panel 1.3D Summary: Ag2255 Two experiments with the same probe and primer set both show highest expression of the CG50379-01 gene, a Frizzled-10 homolog, in samples derived from fetal skeletal muscle (CTs=29-30). Furthermore, expression in fetal skeletal muscle is significantly higher than in adult skeletal muscle (CTs=38). Thus, expression of this gene could be used to differentiate between fetal and adult skeletal muscle. In addition, the significantly higher levels of expression in fetal skeletal muscle suggest that this gene product may enhance muscular growth or development in the fetus and thus may also act in a regenerative capacity in the adult. Therefore, therapeutic modulation of the protein encoded by this gene could be useful in treatment of muscle related diseases. More specifically, treatment of weak or dystrophic muscle with the protein encoded by this gene could restore muscle mass or function.

The CG50379-01 gene is also expressed in small cell lung cancer and colon carcinoma. Therefore, expression of this gene could be used to differentiate between these samples and other samples on this panel. Furthermore, therapeutic targeting of FZD10 with a monoclonal antibody is anticipated to limit or block the extent of tumor cell migration, invasion and growth, specifically in lung and colon tumors.

In the above reference, the Frizzled genes are found to encode WNT receptors. Frizzled-10 (FZD10) was cloned and characterized. Nucleotide sequence analysis showed that human FZD10 gene encodes a seven-transmembrane-receptor of 581 amino acids, with an N-terminal cysteine-rich domain and a C-terminal Ser/Thr-Xxx-Val motif. Larger amounts of FZD10 mRNA, 4.0 kb in size, were detected in the placenta and fetal kidney, followed by fetal lung and brain. In adult brain, FZD10 mRNA was abundant in the cerebellum. Among cancer cell lines, FZD10 was highly expressed in a cervical cancer cell line, HeLa S3, and moderately in a colon cancer cell line, SW480. The FZD10 gene was mapped to human chromosome 12q24.33.

Abstract: The dorsal ectoderm of the limb bud is known to regulate anterior-posterior patterning as well as dorsal-ventral patterning during vertebrate limb morphogenesis. Wnt-7a, expressed in the dorsal ectoderm, encodes a key molecule implicated in these events. In the present study, chicken frizzled-10 (Fz-10) encoding a Wnt receptor was used to study mechanisms of Wnt-7a signaling during chick limb patterning, because its expression is restricted to the posterior-distal region of the dorsal limb bud. Fz-10 transcripts colocalize with Sonic hedgehog (Shh) in the dorsal side of stages 18-23 chick limb buds. It was demonstrated that Fz-10 interacts with Wnt-7a to induce synergistically the expression of Wnt-responsive genes, such as Siamois and Xnr3, in Xenopus animal cap assays. In the chick limb bud, Fz-10 expression is regulated by Shh and a signal from the dorsal ectoderm, presumably Wnt-7a, but not by signals from the apical ectodermal ridge. These results suggest that Fz-10 acts as a receptor for Wnt-7a and has a positive effect on Shh expression in the chick limb bud.

Panel 2D Summary: Ag2255 Two experiments with the same probe and primer set both show highest expression of the CG50379-01 gene, a Frizzled-10 homolog, in samples derived from uterine and lung cancer (CTs=30-31). Significant expression is also seen in prostate cancer. In addition, this gene is overexpressed in uterine, lung and gastric tumors compared with their normal adjacent tissue. Therefore, therapeutic targeting of FZD10 with a monoclonal antibody is anticipated to limit or block the extent of tumor cell migration, invasion and growth, preferably in lung, uterine, prostate, gastric and ovarian tumors.

Panel 3D Summary: Ag2255 The expression of the CG50379-01 gene appears to be highest in a sample derived from a lung cancer cell line (LX-1)(CT=30.7). There also appears to be substantial expression in other lung cancer cell lines as well as colon cancer cell lines. This expression is consistent with the expression seen in Panel 1.3D. Thus, the expression of this gene could be used to distinguish LX-1 samples from other samples in the panel. Moreover, therapeutic modulation of the gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial in the treatment of lung or colon cancer.

Panel 4D Summary: Ag2255 Two experiments with the same probe and primer set both show highest expression of the CG50379-01 gene, a Frizzled-10 homolog, in samples derived from the pulmonary mucoepidermoid cell line NCI-H292 stimulated with IL-4 (CTs=30). Significant expression is also seen in IL-13 activated NCI-H292. This prominent expression in lung-derived tissue is consistent with the previous panels and particularly expression in this cell line is consistent with the expression in AI_comprehensive panel_v1.0. Thus, this expression profile indicates that this gene product may play a key role as a mediator of inflammation, especially in late-phase allergic reactions, and as a mediator of local cellular movement or trafficking into the inflamed area by cytokines and chemokines. Therefore, therapeutic targeting of CG50379-01 with a monoclonal antibody or small molecule drug that antagonize the action of this 7-membrane receptor homolog is anticipated to limit or block the extent of inflammation potential and thus the symptoms, caused by pro-inflammatory cytokines such as IL-4 or IL-13, when these cytokines are induced in allergic, asthma and COPD patients.

Abstract: Interleukin (IL)-9 has recently been shown to play an important role in allergic disease because its expression is strongly associated with the degree of airway responsiveness and the asthmatic-like phenotype. IL-9 is a pleiotropic cytokine that is active on many cell types involved in the allergic immune response. Mucus hypersecretion is a clinical feature of chronic airway diseases; however, the mechanisms underlying the induction of mucin are poorly understood. In this report, it is shown that IL-9 regulates the expression of a subset of mucin genes in lung cells both in vivo and in vitro. In vivo, the constitutive expression of IL-9 in transgenic mice results in elevated MUC2 and MUC5AC gene expression in airway epithelial cells and periodic acid-Schiff-positive staining (reflecting mucous glycogenates). Similar results were observed in C57BL/6J mice after IL-9 intratracheal instillation. In contrast, instillation of the T helper 1-associated cytokine interferon gamma failed to induce mucin production. In vitro, our studies showed that IL-9 also induces expression of MUC2 and MUC5AC in human primary lung cultures and in the human muccoepidermoid NCI-H292 cell line, indicating a direct effect of IL-9 on inducing mucin expression in these cells. Altogether, these results suggest that upregulation of mucin by IL-9 might contribute to the pathogenesis of human inflammatory airway disorders, such as asthma. These data extend the role of the biologic processes that IL-9 has on regulating the many clinical features of asthma and further supports the IL-9 pathway as a key mediator of the asthmatic response.

Abstract: Cigarette smoke exposure is the major cause of chronic obstructive pulmonary disease (COPD). However, only a minority of smokers develop significant COPD, and patients with asthma or asthma-like airway hyperresponsiveness or eosinophilia experience accelerated loss of lung function after cigarette smoke exposure. Pulmonary inflammation is a characteristic feature of lungs from patients with COPD. Surprisingly, the mediators of this inflammation and their contributions to the pathogenesis and varied natural history of COPD are not well defined. Here it is shown that IL-13, a critical cytokine in asthma, causes emphysema with enhanced lung volumes and compliance, mucus metaplasia, and inflammation, when inducibly overexpressed in the adult murine lung. MMP-2, -9, -12, -13, and -14 and cathepsins B, S, L, H, and K were induced by IL-13 in this setting. In addition, treatment with MMP or cysteine proteinase antagonists significantly decreased the emphysema and inflammation, but not the mucus in these animals. These studies demonstrate that IL-13 is a potent stimulator of MMP and cathepsin-based proteolytic pathways in the lung. They also demonstrate that IL-13 causes emphysema via a MMP- and cathepsin-dependent mechanism(s) and highlight common mechanisms that may underlie COPD and asthma.

CNS_neurodegeneration_v1.0 Summary: Ag692 Expression of the CG55023-01 gene is low/undetectable in all samples on this panel (CTs>35). (Data not shown.)

Panel 1 Summary: Ag264/Ag264b Results of three experiments with the CG55023-01 gene show reasonable concordance. The expression of this gene is found to be highest in a sample derived from a prostate cancer cell line (CTs=24-26). In addition, there is substantial expression in a lung cancer cell line. Thus, the expression of this gene could be used to distinguish this prostate cell line sample from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be of benefit in the treatment of prostate or lung cancer.

Panel 1.2 Summary: Ag692 The expression of the CG55023-01 gene was assessed in two independent runs in this panel with excellent concordance between the results. The expression of this gene is found to be highest in a sample derived from a prostate cancer cell line (CTs=23-24). In addition there is substantial expression in a lung cancer cell line. This expression profile is consistent with the expression seen in Panel 1. Thus, the expression of this gene could be used to distinguish this prostate cell line sample from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be of benefit in the treatment of prostate or lung cancer.

This gene also shows moderate expression in all CNS regions examined. TGF alpha has numerous roles in the CNS, including regulation of astrocyte reactivity, neuronal differentiation and survival, and protection of motor neurons. Because of its possible neuroprotective effects, this molecule may be of use in the treatment of multiple sclerosis, ALS, Alzheimer's, Parkinson's, or Huntington's diseases, stroke, or brain or spinal cord trauma.

In addition, this gene is moderately expressed in pancreas, adrenal, thyroid, pituitary, skeletal muscle, and adult and fetal liver. Thus, this gene product may be a monoclonal antibody target for the treatment of metabolic and endocrine disease, including obesity and Types 1 and 2 diabetes. Among metabolic tissues, this gene has highest expression in heart (CT values=27-29), and is 79% identical to mouse epigen protein. Epigen stimulates epithelial cell proliferation (see Panel 4 ref.), suggesting that a monoclonal antibody to this gene product may also be usefull for prevention of cardiomyocyte proliferation in diseases of cardiac hypertrophy.

Expression of transforming growth factor alpha (TGFalpha), a member of the epidermal growth factor (EGF) family, is a general response of adult murine motoneurons to genetic and experimental lesions, TGFalpha appearing as an inducer of astrogliosis in these situations. Here we address the possibility that TGFalpha expression is not specific to pathological situations but may participate to the embryonic development of motoneurons. mRNA of TGFalpha and its receptor, the EGF receptor (EGFR), were detected by ribonuclease protection assay in the ventral part of the cervical spinal cord from embryonic day 12 (E12) until adult ages. Reverse transcription-PCR amplification of their transcripts from immunopurified E15 motoneurons, associated with in situ double-immunohistological assays, identified embryonic motoneurons as cellular sources of the TGFalpha-EGFR couple. In vitro, TGFalpha promoted the survival of immunopurified E15 motoneurons in a dose-dependent manner, with a magnitude similar to BDNF neuroprotective effects at equivalent concentrations. In a transgenic mouse expressing a human TGFalpha transgene under the control of the metallothionein 1 promoter, axotomy of the facial nerve provoked significantly less degeneration in the relevant motor pool of 1-week-old mice than in wild-type animals. No protection was observed in neonates, when the transgene exhibits only weak expression levels in the brainstem. In conclusion, our results point to TGFalpha as a physiologically relevant candidate for a neurotrophic role on developing motoneurons. Its expression by the embryonic motoneurons, which also synthesize its receptor, suggests that this chemokine is endowed with the capability to promote motoneuron survival in an autocrine-paracrine manner.

Xian C J, Zhou X F .Roles of transforming growth factor-alpha and related molecules in the nervous system. Mol Neurobiol 1999 October-December; 20, (2-3):157-83

The epidermal growth factor (EGF) family of polypeptides is regulators for tissue development and repair, and is characterized by the fact that their mature forms are proteolytically derived from their integral membrane precursors. This article reviews roles of the prominent members of the EGF family (EGF, transforming growth factor-alpha [TGF-alpha] and heparin-binding EGF [HB-EGF]) and the related neuregulin family in the nerve system. These polypeptides, produced by neurons and glial cells, play an important role in the development of the nervous system, stimulating proliferation, migration, and differentiation of neuronal, glial, and Schwann precursor cells. These peptides are also neurotrophic, enhancing survival and inhibiting apoptosis of post-mitotic neurons, probably acting directly through receptors on neurons, or indirectly via stimulating glial proliferation and glial synthesis of other molecules such as neurotrophic factors. TGF-alpha, EGF, and neuregulins are involved in mediating glial-neuronal and axonal-glial interactions, regulating nerve injury responses, and participating in injury-associated astrocytic gliosis, brain tumors, and other disorders of the nerve system. Although the collective roles of the EGF family (as well as those of the neuregulins) are shown to be essential for the nervous system, redundancy may exist among members of the EGF family.

Junier M P. What role(s) for TGFalpha in the central nervous system? Prog Neurobiol 2000 December; 62(5):443-73

Transforming growth factor alpha (TGFalpha) is a member of the epidermal growth factor (EGF) family with which it shares the same receptor, the EGF receptor (EGFR or erbB1). Identified since 1985 in the central nervous system (CNS), its functions in this organ have started to be determined during the past decade although numerous questions remain unanswered. TGFalpha is widely distributed in the nervous system, both glial and neuronal cells contributing to its synthesis. Although astrocytes appear as its main targets, mediating in part TGFalpha effects on different neuronal populations, results from different studies have raised the possibility for a direct action of this growth factor on neurons. A large array of experimental data have thus pointed to TGFalpha as a multifunctional factor in the CNS. This review is an attempt to present, in a comprehensive manner, the very diverse works performed in vitro and in vivo which have provided evidences for (i) an intervention of TGFalpha in the control of developmental events such as neural progenitors proliferation/cell fate choice, neuronal survival/differentiation, and neuronal control of female puberty onset, (ii) its role as a potent regulator of astroglial metabolism including astrocytic reactivity, (iii) its neuroprotective potential, and (iv) its participation to neuropathological processes as exemplified by astroglial neoplasia. In addition, informations regarding the complex modes of TGFalpha action at the molecular level are provided, and its place within the large EGF family is precised with regard to the potential interactions and substitutions which may take place between TGFalpha and its kindred.

Panel 2D Summary: Ag264/692 The expression of the CG55023-01 gene was assessed in two independent runs on panel 2D using two different probe/primer pairs. The expression of this gene appears to be highest in samples derived from lung cancer tissue (CTs=28-30). In addition, there is substantial expression in samples derived from two breast cancers, bladder cancer and a sample of normal ovarian tissue. Thus, the expression of this gene could be used to distinguish these lung cancer samples from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics may be of benefit to the treatment of lung cancer, breast cancer or bladder cancer.

Panel 4D Summary: Ag692 The CG55023-01, a TGF-alpha-like Epigen protein homolog, is most highly expressed in small airway epithelium activated with TNFalpha+IL-1beta (CT=28.71) and in KU-812 basophil cells activated with phorbol ester and ionomycin (CT=29.76). Epigne has been shown to stimulate the growth of epithelial cells. Therefore, antibodies that block the action of the CG55023-01 gene product may be useful as therapeutics to reduce or eliminate the symptoms in patients with asthma, emphysema, and allergy

High throughput sequencing of a mouse keratinocyte library was used to identify an expressed sequence tag with homology to the epidermal growth factor (EGF) family of growth factors. We have named the protein encoded by this expressed sequence tag Epigen, for epithelial mitogen. Epigen encodes a protein of 152 amino acids that contains features characteristic of the EGF superfamily. Two hydrophobic regions, corresponding to a putative signal sequence and transmembrane domain, flank a core of amino acids encompassing six cysteine residues and two putative N-linked glycosylation sites. Epigen shows 24-37% identity to members of the EGF superfamily including EGF, transforming growth factor alpha, and Epiregulin. Northern blotting of several adult mouse tissues indicated that Epigen was present in testis, heart, and liver. Recombinant Epigen was synthesized in Escherichia coli and refolded, and its biological activity was compared with that of EGF and transforming growth factor alpha in several assays. In epithelial cells, Epigen stimulated the phosphorylation of c-erbB-1 and mitogen-activated protein kinases and also activated a reporter gene containing enhancer sequences present in the c-fos promoter. Epigen also stimulated the proliferation of HaCaT cells, and this proliferation was blocked by an antibody to the extracellular domain of the receptor tyrosine kinase c-erbB-1. Thus, Epigen is the newest member of the EGF superfamily and, with its ability to promote the growth of epithelial cells, may constitute a novel molecular target for wound-healing therapy.

General_screening_panel_v1.5 Summary: Ag1148 The expression of the CG55688-01 gene appears to be highest in a sample derived from a melanoma cell line (Hs.688(A).T)(CT=32.2). Overall, significant expression is predominantly seen in cancer cell lines, including a related melanoma cell line (Hs.688(B).T), as well as a cluster of renal, ovarian and breast cancer cell lines. Thus, the expression of this gene could be used to distinguish Hs.688(A). T cells from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be of benefit in the treatment of melanoma, renal cancer, breast cancer or ovarian cancer.

There is also significant expression in kidney (CT=33.2) when compared to expression in fetal kidney (CT=38.2). Thus, expression of this gene could be used to differentiate between adult and fetal kidney.

Panel 1.2 Summary: Ag1148 Two experiments with the same probe and primer set show highest expression of the CG55688-01 gene in fetal and adult heart (CTs=25). This gene has moderate to high expression in other metabolic tissues, including pancreas, adrenal, thyroid, pituitary, skeletal muscle and adult and fetal liver. This gene product belongs to the insulin-like growth factor binding protein family and, by homology, may play myriad roles in metabolic regulation. Therefore, this gene product may be a monoclonal antibody target for the treatment of metabolic and endocrine diseases, including obesity and Types 1 and 2 diabetes.

This panel shows that the expression of this gene within the CNS is the highest in the hippocampus. The hippocampus is a region of the brain critical for the formation of long-term memories. Please see panel 1.3d for a discussion of utility of this gene in the central nervous system.

There is also significant expression in lung (CTs=25-27) when compared to expression in fetal lung (CTs=29-30). Thus, expression of this gene could be used to differentiate between adult and fetal lung.

Panel 1.3D Summary: Ag1148 The expression of the CG55688-01 gene appears to be highest in a sample derived from a melanoma cell line (Hs.688(A).T) (CT=27). In addition, there appears to be substantial expression in a related melanoma cell line (Hs.688(B).T) as well as a cluster of brain cancer cell lines and renal cancer cell lines. This expression is consistent with expression in the previous panels. Thus, the expression of this gene could be used to distinguish Hs.688(A).T cells from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be of benefit in the treatment of melanoma, renal cancer or brain cancer.

This panel shows significant expression of this gene in metabolic tissues, confirming expression seen in Panel 1.2. Please see that panel for discussion of the utility of this gene in metabolic disease.

In addition, this gene is expressed at low levels in several brain regions including hippocampus, cortex, substantia migra, thalamus, amygdala, and the fetal brain. Cry61 is an immediate early gene that has been implicated in memory formation and synaptic plasticity. It has also been shown to be upregulated during the development of the hippocampus, which is a critical brain region for the formation of long-term memory. Based on its homology to Cry61 and its preferential expression in the hippocampus, this gene is therefore an excellent drug target for the treatment of dementia (Alzheimer's, vascular, etc) or for memory enhancement.

In brain, muscarinic acetylcholine receptors (mAChRs) modulate neuronal functions including long term potentiation and synaptic plasticity in neuronal circuits that are involved in learning and memory formation. To identify mAChR-inducible genes, we used a differential display approach and found that mAChRs rapidly induced transcription of the immediate early gene CYR61 in HEK 293 cells with a maximum expression after 1 h of receptor stimulation. CYR61 is a member of the emerging CCN gene family that includes CYR61/CEF10, CTGF/FISP-12, and NOV; these encode secretory growth regulatory proteins with distinct functions in cell proliferation, migration, adhesion, and survival. We found that CYR61, CTGF, and NOV were expressed throughout the human central nervous system. Stimulation of mAChRs induced CYR61 expression in primary neurons and rat brain where CYR61 mRNA was detected in cortical layers V and VI and in thalamic nuclei. In contrast, CTGF and NOV expression was not altered by mAChRs neither in neuronal tissue culture nor rat brain. Receptor subtype analyses demonstrated that m1 and m3 mAChR subtypes strongly induced CYR61 expression, whereas m2 and m4 mAChRs had only subtle effects. Increased CYR61 expression was coupled to mAChRs by both protein kinase C and elevations of intracellular Ca(2+). Our results establish that CYR61 expression in mammalian brain is under the control of cholinergic neurotransmission; it may thus be involved in cholinergic regulation of synaptic plasticity.

Chung K C, Ahn Y S. Expression of immediate early gene cyr61 during the differentiation of immortalized embryonic hippocampal neuronal cells. Neurosci Lett Oct. 23, 1998; 255(3):155-8

Growth factor-mediated signal transduction is a process that is of fundamental importance in understanding cellular growth and differentiation. In order to elucidate the signaling pathways leading to neuronal differentiation, we have tried to identify intermediates that are selectively induced in the differentiation of immortalized neuronal hippocampal cell line H19-7. In the present study we found that immediate early gene cyr61 is expressed in a rapid and transient manner by bFGF during the differentiation of H19-7 cells. To clarify the signal transduction pathway for the induction of cyr61 by bFGF, we checked whether Raf-1 and mitogen-activated protein kinase (MAPK) is activated during the induction of cyr61. It is identified that cyr61 is induced by bFGF via at least two signaling pathways; MAPK-dependent as well as MAPK-independent signaling pathways. This study suggested that cyr61 is likely to play an important role in neuronal differentiation process.

Panel 2D Summary: Ag1148 The expression of the CG55688-01 gene was assessed in two independent runs in panel 2D with excellent concordance between runs. The highest expression of this gene is found in normal bladder tissue and a kidney cancer sample (CTs=28). In addition, there appears to be substantial expression associated with ovarian derived tissue, prostate derived tissue and a number of kidney samples. Thus, the expression of this gene could be used to distinguish the bladder and kidney samples from the rest of the samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be beneficial in the treatment of kidney cancer, ovarian cancer or prostate cancer.

Panel 3D Summary: Ag1148 The expression of the CG55688-01 gene appears to be highest in a sample derived from a lung cancer (NCI-H292)(CT=28). In addition, there is substantial expression associated with a number of brain cancers, renal cancer cell lines, pancreatic cancer cell lines, bladder cancer cell lines and two sarcoma cell lines. Thus, the expression of this gene could be used to distinguish NCI-H292 cells from the other samples in the panel.

Panel 4D Summary: Ag1148 The CG55688-01 gene, a Cyr61 homolog, is expressed at moderate levels (CT range 28-32), in resting and cytokine-stimulated HUVEC, lung microvascular endothelial cells, coronary artery smooth muscle cells, bronchial epithelial cells, small airway epithelial cells, astrocytes, pulmonary artery endothelial cells, lung fibroblasts, and dermal fibroblasts. Based on the expression pattern above and our understanding of the functions of Cyr61 in vascular biology (see reference), it can be concluded that antibodies and small molecule antagonists that block the function of the CG55688-01 gene product may reduce or eliminate the symptoms in patients with any of several inflammatory or autoimmune diseases, including Crohn's disease, ulcerative colitis, multiple sclerosis, chronic obstructive pulmonary disease, asthma, emphysema, rheumatoid arthritis, or psoriasis.

CYR61 is a secreted, cysteine-rich, heparin-binding protein encoded by a growth factor-inducible immediate-early gene. Acting as an extracellular, matrix-associated signaling molecule, CYR61 promotes the adhesion of endothelial cells through interaction with the integrin alphaVbeta3 and augments growth factor-induced DNA synthesis in the same cell type. In this study, we show that purified CYR61 stimulates directed migration of human microvascular endothelial cells in culture through an alphaV beta3-dependent pathway and induces neovascularization in rat corneas. Both the chemotactic and angiogenic activities of CYR61 can be blocked by specific anti-CYR61 antibodies. Whereas most human tumor-derived cell lines tested express CYR61, the gastric adenocarcinoma cell line RF-1 does not. Expression of the CYR61 cDNA under the regulation of a constitutive promoter in RF-1 cells significantly enhances the tumorigenicity of these cells as measured by growth in immunodeficient mice, resulting in tumors that are larger and more vascularized than those produced by control RF-1 cells. Taken together, these results identify CYR61 as an angiogenic inducer that can promote tumor growth and vascularization; the results also suggest potential roles for CYR61 in physiologic and pathologic neovascularization.

Panel 5 Islet Summary:: Ag1148 The CG55688-01 gene has low expression in islet tissue. It is also expressed at low levels in mesenchymal stem cells, which can be differentiated in vitro into adipocytes, chondrocytes and osteocytes. Therefore, this gene may be a monoclonal antibody target for the treatment of diseases involving adipose, cartilage or bone.

Panel 1.2 Summary: Ag1102 Highest expression of the CG56157-01 gene is seen in skeletal muscle (CT=24), with high levels of expression also seen in pancreas, adrenal, pituitary, heart, and liver. Diazepam binding inhibitor (DBI) is a 10-kDa polypeptide that regulates mitochondrial steroidogenesis, glucose-induced insulin secretion, metabolism of acyl-CoA esters, fatty acid oxidation, and the action of gamma-aminobutyrate on GABAA receptors. This gene, a DBI-related protein, may thus be a small molecule target for the treatment of metabolic and endocrine diseases, including obesity and Types 1 and 2 diabetes.

This gene also expressed at high levels in all CNS regions examined. The diazepam binding inhibitor has been implicated in seizure disorders, drug dependence and memory. In addition, this ligand acts at the CIABA-A receptor which has been implicated in schizophrenia and bipolar disorder. Therefore, therapeutic modulation of this gene, a diazepam binding inhibitor homolog, may be of use in any of these clinical conditions.

Diazepam binding inhibitor (DBI) is a 10-kDa polypeptide that regulates mitochondrial steroidogenesis, glucose-induced insulin secretion, metabolism of acyl-CoA esters, and the action of gamma-aminobutyrate on GABAA receptors. To investigate the regulation of DBI gene expression, three positive clones were isolated from a rat genomic library. One of them contained a DBI genomic DNA fragment encompassing 4 kb of the 5′ untranslated region, the first two exons, and part of the second intron of the DBI gene. Two other overlapping clones contained a processed DBI pseudogene. Several transcription initiation sites were detected by RNase protection and primer extension assays. Different tissues exhibited clear differences in the efficiencies of transcription startpoint usage. Transient expression experiments using DNA fragments of different length from the 5′ untranslated region of the DBI gene showed that basal promoter activity required 146 bp of the proximal DBI sequence, whereas full activation was achieved with 423 bp of the 5′ untranslated region. DNase I protection experiments with liver nuclear proteins demonstrated three protected regions at nt −387 to −333, −295 to −271, and −176 to −139 relative to the ATG initiation codon; in other tissues the pattern of protection was different. In gel shift assays the most proximal region (−176 to −139) was found to bind several general transcription factors as well as cell type-restricted nuclear proteins which may be related to specific regulatory patterns in different tissues. Thus, the DBI gene possesses some features of a housekeeping gene but also includes a variable regulation which appears to change with the function that it subserves in different cell types.

The polypeptide diazepam binding inhibitor (DBI) displays epileptogenic activity by binding to benzodiazepine receptors. We analyzed DBI concentrations in the plasma of pediatric and adult epileptic patients, as a possible peripheral marker in epilepsy. DBI plasma concentrations are significantly higher (+62%, P<0.001) in adult patients and slightly but significantly higher (+15%, P<0.01) in pediatric patients, compared to age-related controls. Strikingly, plasma DBI is much higher (+81%, P<0.001) in generalized epilepsy in adults and in drug-resistant pediatric and adult patients. Based on these findings, plasma DBI may be considered as a peripheral biological marker of epilepsy and, in association with lymphocyte benzodiazepine receptor density, of anticonvulsant drug responsiveness.

Herzog C D, Stackman R W, Walsh T J. Intraseptal flumazenil enhances, while diazepam binding inhibitor impairs, performance in a working memory task. Neurobiol Learn Mem 1996 November; 66(3):341-52

GABAA/benzodiazepine receptors in the medial septum modulate the activity of cholinergic neurons that innervate the hippocampus. Injection of benzodiazepine (BDZ) agonists into the medial septum impairs working memory performance and decreases high-affinity choline transport (HAChT) in the hippocampus. In contrast, intraseptal injection of the BDZ antagonist flumazenil increases HAChT and prevents the memory deficits induced by systemic BDZs. The present studies attempted to further characterize the behavioral effects of medial septal injections of flumazenil to an endogenous negative modulator of the GABAA/BDZ receptor complex, diazepam binding inhibitor (DBI). Male Sprague-Dawley rats were cannulated to study the effects of intraseptal injections of these BDZ ligands on spatial working memory, anxiety-related behaviors in the elevated plus maze, and on general locomotor activity. Intraseptal flumazenil (10 nmol/0.5 microliter) produced a delay-dependent enhancement of DNMTS performance after an 8-h, but not a 4-h, delay interval. This promnestic dose of flumazenil had no effect on locomotor activity and did not produce changes in measures of anxiety on the plus maze. Intraseptal injection of DBI had no effect (8 nmol/0.5 microliter) or slightly impaired (4 nmol/0.5 microliter) DNMTS radial maze performance following an 8-h delay, without producing changes in locomotion or plus maze behavior. These data demonstrate that flumazenil has a unique profile of activity in enhancing working memory following intraseptal injection.

Ohkuma S, Katsura M, Tsujimura A. Alterations in cerebral diazepam binding inhibitor expression in drug dependence: a possible biochemical alteration common to drug dependence. Life Sci Feb. 2, 2001; 68(11):1215-22

Mechanisms for formation of drug dependence and expression of withdrawal syndrome have not fully clarified despite of huge accumulation of experimental and clinical data at present. Several clinical features of withdrawal syndrome are considered to be common among patients with drug dependence induced by different drugs of abuse. One of them is anxiety. Recent investigations have revealed that diazepam binding inhibitor (DBI), a peptide consisting of 87 amino acids with molecular weight of about 10 kDa, serves as an inverse agonist for benzodiazepine (BZD)) receptors with endogenously anxiogenic potential. These lines of data suggest that cerebral DBI expression in brain may participates in formation of drug dependence and/or emergence of withdrawal syndrome. Based on this working hypothesis, we have examined DBI expression in the brain derived from mice depended on alcohol (ethanol), nicotine, and morphine to investigate functional relationship between cerebral DBI expression and drug dependence. Cerebral DBI expression significantly increases in animals with drug dependence induced by these drugs, and in the cases of nicotine- and morphine-dependent mice concomitant administration of antagonists for nicotinic acetylcholine and opioid receptors, respectively, abolished the increase. Abrupt cessation of administration of drugs facilitated further increase in DBI expression. Therefore, these alterations in DBI expression have close relationship with formation of drug dependence and/or emergence of withdrawal syndrome, and are considered to be a common biochemical process in drug dependence induced by different drugs of abuse. Finding and elucidation of mechanisms for common biochemical alterations among drug dependence may provide a clue to clarify mechanisms for formation of drug dependence and/or emergence of withdrawal syndrome.

General_screening_panel_v1.4 Summary: Ag2044 The expression of the CG54933-01 gene appears to be highest in a sample derived from a gastric cancer cell line (NCI-N87)(CT=25.1). In addition, there is substantial expression in ovarian cancer cell lines, a pancreatic cancer cell line and colon cancer cell lines. Thus, the expression of this gene could be used to distinguish NCI-N87 cells from the rest of the samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, monoclonal antibodies or protein therapeutics might be beneficial for the treatment of colon cancer, gastric cancer, pancreatic cancer or ovarian cancer.

The expression of the isoform of this gene in endocrine/metabolically-related tissues is restricted to adipose, pancreas and small intestine. Due to its presumed role in cell adhesion and the moderate level of expression in adipose this gene and/or gene product may be a target in the treatment of obesity.

Panel 1.3D Summary: Ag2044 The expression of the CG54933-01 gene was assessed in two independent runs on panel 1.3D with excellent concordance between the runs. The expression of this gene is highest in a sample derived from a gastric cancer cell line (NCI-N87)(CTs=28), consistent with the expression in General_screening_panel_v1.4. In addition, there is substantial expression observed in colon cancer cell lines, ovarian cancer cell lines, normal lung tissue, a liver cancer sample and a sample derived from a pancreatic cancer cell line. Thus, the expression of this gene could be used to distinguish NCI-N87 cells from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial for the treatment of colon cancer, gastric cancer, pancreatic cancer, liver cancer or ovarian cancer.

Panel 2D Summary: Ag2044 The expression of the CG54933-01 gene was assessed in two independent runs on panel 2D with excellent concordance between the runs. Overall, the expression of this gene is highest in samples derived from ovarian cancer tissue (CTs=25). This gene encodes a protein that is homologous to mesothelin, which has been shown to be up-regulated in ovarian cancer. In addition, there is substantial expression observed in metastatic colon cancer derived tissue, lung derived tissue and gastric cancer derived tissue. Thus, the expression of this gene could be used to distinguish the above mentioned tissues from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial for the treatment of colon cancer, gastric cancer, lung cancer or ovarian cancer.

Mesothelin, a differentiation antigen, is a 40-kD glycosylphosphatidylinositol-linked cell-surface glycoprotein, that is present on the surface of normal mesothelium and is overexpressed in many patients with epithelial ovarian cancer and malignant mesotheliomas. Monoclonal antibody K1 is a murine immunoglobulin G1 that recognizes mesothelin. LysPE38QQR is a truncated form of Pseudomonas exotoxin that lacks the cell-binding domain, but retains the translocation and adenosine diphosphate-ribosylation domains. It has a single lysine residue near the amino terminus that is available for conjugation to antibodies. To prevent chemical conjugation of the antibody to lysine residues at the C-terminus of Pseudomonas exotoxin, the two lysine residues at positions 590 and 606 were mutated to glutamine, and the lysine residue at position 613 was mutated to arginine. Monoclonal antibody K1 was chemically conjugated with LysPE38QQR, by modifying the antibody with sulfosuccinimidyl-4-(N-maleimicdomethyl)cyclohexane-1-carboxylate and coupling it with SPDP N-succinimidyl 3-(2-pyridyldithio)propionate-modified LysPE38QQR. The resulting immunotoxin K1-LysPE38QQR was highly toxic to A431-K5 cells (a human epidermoid carcinoma cell line transfected with a mesothelin expression plasmid) with a half-maximal inhibitory concentration of 3-6 ng/mL. The immunotoxin had negligible activity against A431 cells, which do not express mesothelin (median inhibitory concentration>100 ng/mL). This immunotoxin also caused complete regression of tumors in nude mice that received xenografts of mesothelin-positive human carcinomas. These results show that immunotoxins directed against mesothelin are a therapeutic option that merits further investigation for the treatment of ovarian cancer and malignant mesotheliomas.

Panel 3D Summary: Ag2044 The expression of the CG54933-01 gene appears to be highest in a sample derived from a lung cancer cell line (DMS-79)(CT=27.8). In addition, there appears to be substantial expression in colon cancer derived cell lines, pancreatic cancer derived cell lines, gastric cancer derived cell lines, lung cancer derived cell lines and cervical cancer derived cell lines. Thus, the expression of this gene could be used to distinguish DMS-79 cells from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial for the treatment of colon cancer, gastric cancer, lung cancer, cervical cancer, or pancreatic cancer.

Panel 4D Summary: Ag2044 The expression of the CG54933-01 gene was assessed in two independent runs using same set of primers. Both runs show moderate expression of this transcript in the NCI H292 cell line, a human airway epithelial cell line that produces mucins. Mucus overproduction is an important feature of bronchial asthma and chronic obstructive pulmonary disease(COPD). This transcript encodes for mesothelin, a cell surface protein, that may play a role in cellular adhesion or in megakaryocyte proliferation. Thus, this gene may be involved in promoting hyperplasia or mucus production in these cell type. Therefore, modulation of the expression or activity of this gene or gene product by antibodies could beneficial for the treatment of these asthma and COPD.

Panel 1.2 Summary: Ag1438 Highest expression of the CG56010-01 gene is seen in breast cancer (CT=20.1), with significant expression also seen in a cluster of lung cancer cell lines. Thus, expression of this gene could be used to differentiate between these samples and other samples on this panel. Furthermore, therapeutic modulation of the expression or function of this gene product through the application of small molecules or monoclonal antibodies may be effective in the treatment of breast and lung cancers.

Panel 1.3D Summary: Ag1438 Two experiments with the same probe and primer set produce results that are in excellent agreement, with highest expression of the CG56010-01 gene in a breast cancer cell line (CTs=27). Significant expression is also seen in a cluster of lung and colon cancer cell lines. This expression is consistent with the expression in Panel 1.2. Thus, expression of this gene could be used to differentiate between these samples and other samples on this panel. Furthermore, therapeutic modulation of the expression or function of this gene product through the application of small molecules or monoclonal antibodies may be effective in the treatment of breast, colon and lung cancers.

There is also moderate expression of this gene in several endocrine/metabolic related tissues, including adrenal, adipose, GI tract, pancreas and thyroid. Therefore, therapeutic modulation of this gene and/or gene-product may be useful in the treatment of diseases that involve the above mentioned tissues.

Panel 2D Summary: Ag1438 Two experiments with the same probe and primer set produce results that are in excellent agreement, with highest expression of the CG56010-01 gene in a lung cancer cell line (CTs=22-24). Significant expression is also seen in samples derived from breast, gastric, bladder, and uterine cancers. Thus, expression of this gene could be used to differentiate between these samples and other samples on this panel. Furthermore, therapeutic targeting of this gene product with a monoclonal antibody is anticipated to limit or block the extent of tumor growth in Subsets of breast cancers, gastric carcinomas. uterian tumors, transitional cell carcinomas of the bladder and lung adenocarcinomas/squamous cell carcinomas. Based on this gene's homology to trefoil 3, restricted normal tissue distribution, and preferential expression in proliferative cell lines seen in the previous panels, this gene product provides an excellent opportunity for drug targeting.

The trefoil peptides spasmolytic polypeptide (SP), intestinal trefoil factor (ITF), and pS2 show lineage-specific expression in the normal gut and are strongly induced after mucosal injury. We assessed the relationship between this induction and the development of the regenerative epithelial lineage over time in the rat stomach and verified these observations in the metaplastic and dysplastic human stomach. Antral or colonic ulcers were induced in Wistar rats by application of serosal acetic acid and tissues harvested 2 hours to 125 days later. Human endoscopic biopsies or gastric resection specimens were also assessed. Tissues were examined by radioimmunoassay, immunoblotting, or immunohistochemistry for ITF, SP, and transforming growth factor alpha (rat) or ITF and pS2 (human) expression. ITF and SP mRNA in antral ulcer margins was localized by in situ hybridization. ITF and SP peptide expression rose steadily in ulcer margins after 4 days, with the rise in ITF being more pronounced. By 40 days, several hundred-fold elevations in ITF levels were present, with a field effect in uninvolved mucosa. Hyperproliferative, elongated glands of undifferentiated cells expressing abundant trefoil peptides and acid sulfomucins were present after day 12 and persisted after ulcer healing. ITF mRNA was aberrantly expressed in basal and mid-regions of these regenerative glands. In contrast, transforming growth factor alpha peptide expression rose promptly after injury then fell to baseline levels with healing. Seven months after injury, gastric atrophy, intestinal metaplasia, and severe dysplasia with conserved ITF expression were seen. ITF was also induced in human intestinal metaplasia and conserved in all gastric cancers, whereas expression of the gastric peptide pS2 was progressively reduced in the progression from metaplasia to dysplasia. Persistent, selective overexpression of ITF, possibly acting in an autocrine fashion, is a feature of regeneration after antral ulceration, and may provide insight into the nature of metaplastic phenotypes arising from chronic gastric injury. The loss of pS2 expression in metaplasia and cancer supports a role for this protein in gastric tumor suppression.

Intestinal trefoil factor controls the expression of the adenomatous polyposis coli-catenin and the E-cadherin-catenin complexes in human colon carcinoma cells. Proc Natl Acad Sci U S A Mar. 17, 1998; 95(6):3122-7

Intestinal trefoil factor 3 (TFF3) is a member of the trefoil family of peptides, small molecules constitutively expressed in epithelial tissues, including the gastrointestinal tract. TFF3 has been shown to promote migration of intestinal epithelial cells in vitro and to enhance mucosal healing and epithelial restitution in vivo. In this study, we evaluated the effect of recombinant TFF3 (rTFF3) stimulation on the expression and cellular localization of the epithelial (E)-cadherin-catenin complex, a prime mediator of Ca2+ dependent cell-cell adhesion, and the adenomatous polyposis coli (APC)-catenin complex in HT29, HCT116, and SW480 colorectal carcinoma cell lines. Stimulation by rTFF3 (10(−9) M and 10(−8) M) for 20-24 hr led to cell detachment and to a reduction in intercellular adhesion in HT29 and HCT116 cells. In both cell lines, E-cadherin expression was down-regulated. The expression of APC, alpha-catenin and beta-catenin also was decreased in HT29 cells, with a translocation of APC into the nucleus. No change in either cell adhesion or in the expression of E-cadherin, the catenins, and APC was detected in SW480 cells. In addition, TFF3 induced DNA fragmentation and morphological changes characteristic of apoptosis in HT29. Tyrphostin, a competitive inhibitor of protein tyrosine kinases, inhibited the effects of TFF3. Our results indicate that by perturbing the complexes between E-cadherin, beta-catenin, and associated proteins, TFF3 may modulate epithelial cell adhesion, migration, and survival.

Panel 3D Summary: Ag1438 Highest expression of the CG56010-01 gene is seen in a lung cancer cell line (CTs=26). Significant expression is also seen in a cluster of gastric and colon cancer cell lines. Thus, expression of this gene could be used to differentiate between these samples and other samples on this panel. Furthermore, therapeutic modulation of the expression or function of this gene product through the application of small molecules or monoclonal antibodies may be effective in the treatment of gastric, colon and lung cancers.

Panel 4D Summary: Ag1438 Highest expression of the CG56010-01 transcript is observed in colon (CT=28.1). This expression is expected considering the nature of the protein encoded by this transcript, the trefoil factor 3 (ref. 1). The expression of this transcript is down regulated in colon from patients suffering from either Crohn's or colitis, suggesting a role for this gene in the normal homeostasis of this tissue. Therefore, agonistic antibodies or protein therapeutics may be beneficial for the the restoration of the normal function of the colon mucosa in inflammatory diseases such as inflammatory bowel disease. Low expression of this transcript is also observed in the microvasculature of the lung and the dermis suggesting a role for this gene in the maintenance of the integrity of the microvasculature. Therefore, therapeutics designed for this putative protein could be beneficial for the treatment of diseases associated with damaged microvasculature including heart diseases or inflammatory diseases, such as psoriasis, asthma, and chronic obstructive pulmonary diseases.

Trefoil factor family domain peptides (TFF) are thought to be involved in mucosal epithelial restitution and wound healing of the gastrointestinal tract and are up-regulated in ulceration and in a variety of solid tumours. It was hypothesized that TFFs are also expressed on mucosal surfaces of the human respiratory tract. Lung tissue, nasal polyps, and sputum samples from seven patients with cystic fibrosis (CF), two with chronic and acute bronchitis, and non-dysplastic material from two cases of bronchial adenocarcinoma were analysed for TFF expression by immunohistochemistry, immunofluorescence, western blot and RT-PCR. Expression of TFF1 and TFF3 was observed in material from all patients. TFFs were localized in goblet and ciliated cells, as well as in some submucosal cells of tracheobronchial tissues and nasal polyps from normal and CF individuals. In sputa of patients with CF and with chronic or acute bronchitis, TFF1 and TFF3 were detected by western blotting. Freshly cultivated nasal epithelial cells transcribed and secreted TFFs and mucins, whereas nasal cells cultivated for 6 weeks still expressed mucins, but not TFFs. Secreted TFFs and mucins also bound to the surface of Staphylococcus aureus in infected CF airways. In conclusion, TFF1 and TFF3 are expressed and secreted in normal and inflamed airways. The association of TFFs with bacteria may contribute to the anti-microbial mucociliary defence system.

Panel 1.2 Summary: Ag1360 The expression of the CG56015-01 gene appears to be highest in a sample derived from normal kidney tissue (CT=20.7). In addition, there appears to be substantial expression in kidney cancer derived cell lines, ovarian cancer derived cell lines, colon cancer derived cell lines and normal salivary gland. Thus, the expression of this gene could be used to distinguish normal kidney from the other samples in the panel. The product of this gene is hypothesized to be involved in cellular communication. Therefore, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial in the treatment of kidney cancer, ovarian cancer or colon cancer.

This gene product also has a moderate to high level of expression in a number of endocrine/metabolically relevant tissues, including brain, GI tract, pituitary, and liver. Thus, therapeutic modulation of this gene product may be useful in the treatment of metabolic disorders, such as obesity and diabetes.

Kocher O, Cheresh P, Lee S W. Identification and partial characterization of a novel membrane-associated protein (MAP17) up-regulated in human carcinomas and modulating cell replication and tumor growth. Am J Pathol. 1996 August; 149(2):493-500.

Using the differential display technique, we have recently reported the identification of a novel gene originally designated DD96. As determined by Northern blot and in situ hybridization, DD96 was expressed at significant levels only in a single epithelial cell population, the proximal tubular epithelial cells of the kidney. However, it was diffusely expressed in various carcinomas originating from kidney, colon, lung, and breast. Using a specific polyclonal antibody, we have not determined that the DD96 protein product is a 17-kd membrane-associated protein, which we have therefore redesignated MAP17. In normal tissues, MAP17 is expressed in significant amounts only in the kidney, where it was localized to the brush border of proximal tubular epithelial cells. However, MAP17 is expressed abundantly in carcinomas arising from kidney, colon, lung, and breast, in some cases with a membrane-associated apical glandular distribution. In tissue culture, MAP17 was localized to the cell membrane in areas of cell-cell contact, ie, the distribution of cell-function-associated proteins. Transfection of a fill-length wild-type DD96 cDNA clone into a colon carcinoma cell line, HT-29, markedly decreased cell proliferation in vitro and tumor growth in vivo. Although the precise function of MAP17 remains to be determined, our findings suggest that this protein may play an important role in tumor biology.

Panel 1.3D Summary: Ag1360 The expression of the CG56015-01 gene appears to be highest in a sample derived from a renal cancer cell line (CT=26.5). In addition, there appears to be substantial expression in other kidney cancer derived cell lines, ovarian cancer derived cell lines, colon cancer tissue, stomach tissue, an astrocytoma cell line a pancreatic cancer cell line and normal kidney and salivary gland. Thus, the expression of this gene could be used to distinguish normal kidney or A498 cells from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, monoclonal antibodies or protein therapeutics may limit or block the extent of tumor cell growth and be beneficial in the treatment of kidney cancer, ovarian cancer or colon cancer.

Panel 2D Summary: Ag1360 The expression of the CG56015-01 gene was assessed in two independent runs in panel 2D with excellent concordance between the runs. Overall, the expression of this gene was highest in normal kidney tissue, a result in concordance with expression in Panels 1.2 and 1.3D. Thus, the expression of this gene could be used to distinguish normal kidney tissue from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial in the treatment of kidney cancer.

Panel 3D Summary: Ag1360 The expression of this gene appears to be highest in a sample derived from a renal cancer cell line (Caki-2). In addition there is substantial expression associated with other kidney cancer cell lines, colon cnacer cell lines and a breast cancer cell line. Thus, the expression of this gene could be used to distinguish Caki-2 cells from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial in the treatment of kidney cancer, breast cancer or colon cancer.

Panel 4.1D Summary: Ag1360 This transcript, encoding for a membrane associated epithelial protein, is highly expressed in kidney (CT 24.4). High expression of this transcript is also found in small airway and bronchial epithelium, (CT 27) and to a lower extent in the mucoepidermoid cell line H292 (CT 29). The protein encoded by this transcript appears to be involved in cell-cell communication and/or proliferation. Therefore modulation of the expression or activity of this putative protein by antibodies may be useful for the treatment of lung diseases associated with hyperplasia and/or activation of mucus producing cells such as asthma, chronic obstructive pulmonary diseases, emphysema and/or lung cancer

CNS_neurodegeneration_v1.0 Summary: Ag1390 Expression of the CG56035-01 gene is low/undetectable (CTs>35) across all of the samples on this panel (data not shown).

Panel 1.2 Summary: Ag1390 The expression of the CG56035-01 gene was assessed in two independent runs in panel 1.2 with good concordance between runs. The expression of this gene appears to be highest in a sample derived from a lung cancer cell line (NCI-H522)(CTs=24). Thus, the expression of this gene could be used to distinguish NCI-H522 cells from other samples in the panel. Frizzled 4 genes, to which this gene is a homolog, act as soluble modulators of Wnt signaling. The WNT signaling cascade is involved in regulation of cytoskeletal rearrangements, apoptosis, and proliferation. Therefore, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be beneficial in the treatment of lung cancer.

The pattern of expression of this isoform of this gene indicates that it may also have an important function in endocrine/metabolic physiology. Moderate to high levels of expression can be found in adrenal, brain, GI tract, pancreas, pituitary and thyroid. Thus, this gene product may be involved in the diagnosis and/or treatment of metabolic disorders, including obesity and diabetes.

In addition, higher levels of expression of this gene in lung (CTs=32-33)and liver (CTs=31-32) than in fetal lung and liver (CTs=36) suggest that it can also be used to differentiate between the adult and fetal forms of lung and liver.

Panel 2D Summary: Ag1390 The expression of the CG56035-0l gene was assessed in two independent runs in panel 2D with excellent concordance between runs. The expression of this gene appears to be highest in a sample derived from an ovarian cancer (CTs=30). In addition, there appears to be substantial expression associated with breast cancer. Thus, the expression of this gene could be used to distinguish this ovarian cancer sample from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be beneficial in the treatment of breast or ovarian cancer.

Panel 3D Summary: Ag1390 Expression of the CG56035-01 gene is low/undetectable (CTs>35) across all of the samples on this panel (data not shown).

Panel 4D Summary: Ag1390 Highest expression of the CG56035-01 transcript is found in secondary Th2 rest cells (CT=31.7), but is absent in other T cells. Expression of this transcript is also found in the lung. This transcript encodes for a secreted frizzled related protein that are reported to antagonize the WNT/frizzled pathway. Since lung inflammatory diseases such as asthma and chronic obstructive pulmonary diseases are mediated by Th2 cells, this protein may be involved in the lung pathology associated with these Th2 T cells. Therefore, therapeutics designed against the protein encoded by this gene may be useful for the treatment of lung inflammatory diseases. This transcript is also expressed in astrocytes treated with TNF-a and IL-1 indicating that therapeutics designed against the protein encoded by this gene may be useful for the treatment of inflammatory CNS diseases such as multiple sclerosis.

CNS_neurodegeneration_v1.0 Summary: Ag1749 This panel does not show differential expression of the CG56153-01 gene in Alzheimer's disease. However, this expression profile confirms the presence of this gene in the brain. Please see Panel 1.3D for discussion of this gene in the central nervous system.

Panel 1.3D Summary: Ag1749 The expression of the CG56153-01 gene is highest in a sample derived from the pituitary gland (CT=28.2). This is in concordance with published reports (see reference below). In addition, there is low but substantial expression in various brain tissues as well as placenta tissue. The expression pattern of this isoform of the neuronatin gene eludes to its developmental importance (see references below). Expression in this gene is higher in fetal lung (CT=33) and skeletal muscle (CT=30) than in the corresponding adult tissues. Thus, the expression of this gene could be used to distinguish pituitary gland tissue from other tissues in the panel. In addition, this gene and/or gene product can be used to differentiate between the adult and fetal forms of skeletal muscle and lung. Furthermore, the expression in fetal tissue suggests that this gene product may be involved in the development of these organs and thus may be useful in treating disease that affect the lung and skeletal muscle. This gene encodes a putative proteolipid that may function as a unique regulator of ion channels during brain development and therefore may also be useful in the treatment of neurodevelopmental disorders.

The authors cloned the nearly complete cDNA of human neuronatin with the aid of an expressed sequence tag (EST) database, and analyzed its expression in various human tissues by Northern blot analysis. The nucleotide and deduced amino acid sequences of the human neuronatin showed a high similarity to those of rodents. The Northern blot analysis revealed that the human neuronatin message was expressed predominantly in the fetal brain in the brain-specific manner, but only faintly in the adult brain. Among the various adult human tissues examined, the anterior pituitary gland was shown to be the only place where the neuronatin mRNA was strongly expressed. Intense neuronatin expression was also observed in several human pituitary adenomas, including ACTH-producing, GH-producing, and nonfunctioning adenomas, but hardly detected in other brain tumors.

Human brain development is a continuum governed by differential gene expression. Therefore, we proceeded to identify genes selectively expressed in the developing brain. Using differential display and library screening, a novel rat cDNA, neuronatin, was identified and used to screen a human fetal brain cDNA library. Human neuronatin cDNA was isolated and sequenced. The cDNA was 1159 bp long and corresponded in size to the 1.25 kb message detected on Northern analysis. Neuronatin mRNA was selectively expressed in human brain during fetal development, but became repressed in adulthood. When studied in the rat, neuronatin mRNA first appeared at mid-gestation in association with the onset of neurogenesis, becoming most pronounced later in development when neuroepithelial proliferation and neuroblast commitment are manifest, and declined postnatally coinciding with the completion of neurogenesis. The deduced protein has two distinct domains, a hydrophobic N-terminal and basic C-terminal rich in arginine residues. Both the amino acid sequence and secondary structure of this amphipathic polypeptide exhibited homology to PMP1 and phospholamban, members of the “proteolipid” class of proteins which function as regulatory subunits of membrane channels. The neuronatin gene, 3973 bases long, contains in its 5′-flanking region a neural restrictive silencer element which may govern neuron-specific expression. Based on screening a somatic cell hybrid panel, neuronatin gene was assigned to chromosome-20. And, using deletion constructs of chromosome-20 and fluorescence in situ hybridization, neuronatin was localized to chromosome-20q11.2-12. In conclusion, neuronatin is a novel human gene that is developmentally regulated and expressed in the brain. The deduced protein is a proteolipid that may function as a unique regulator of ion channels during brain development. The definitive localization of neuronatin to human chromosome 20q11.2-12 provides the basis to investigate this gene as a candidate in neuro-developmental diseases that may also map to this region.

Panel 2D Summary: Ag1749 The expression of the CG56153-01 gene appears to be highest in a sample derived from normal bladder tissue adjacent to a bladder malignancy (CT=33.6). In addition, there is substantial expression associated with normal stomach tissue, breast tissue and a number of normal colon tissue samples adjacent to malignant colon. This preferential expression in normal tissue samples is in agreement with the expression in Panel 1.3D. Thus, the expression of this gene could be used to distinguish this normal bladder tissue sample from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial in the treatment of colon cancer, bladder cancer, breast cancer or gastric cancer.

Panel 4D Summary: Ag1749 The CG56153-01 gene, a neuronatin homolog is expressed at moderate to low levels in HUVEC cells resting, serum-starved, and activated with IFN-gamma as well as resting astrocytes and kidney (CTs=32.8-33.44). This putative protein product is a proteolipid that may function as a regulator of ion channels in these cells and tissues, similar to its putative function in brain development. Antibodies and small molecules that antagonize the function of the CG56153-01 product may reduce or eliminate the symptoms in patients with autoimmune and inflammatory diseases in which endothelial cells and astrocytes are involved, such as lupus erythematosus, asthma, emphysema, Crohn's disease, ulcerative colitis, multiple sclerosis, rheumatoid arthritis, osteoarthritis, and psoriasis.

Panels 5 Islet and 5D Summary: Ag1749 The expression pattern of the CG56153-01 gene, which encodes a neuronatin isoform, indicates an importance in placental function and regulation. The placental tissue samples were collected from nondiabetic obese women (patients 7 and 9), a diabetic patient on insulin and classified as overweight (patient 10), and finally a women diagnosed with diabetes and on insulin (patient 12). Furthermore, the expression of this gene in placenta confirms the importance of the gene product in the development of the fetus.

Panel 1.3D Summary: Ag1910/Ag2047 Three experiments with the same probe and primer set produce results that are in excellent agreement, with highest expression of the CG56159-01 gene in a breast cancer cell line (BT549)(CTs=24-25). Thus, expression of this gene could be used to distinguish BT549 cells from other samples in the panel. There is also significant expression in clusters of cell lines derived from renal cancer, brain cancer and melanoma. This gene encodes a homolog of aminopeptidase N, which is thought to be critical in the metastasis of cancer by degrading extracellular matrix and aiding in cellular motility. Thus, therapeutic modulation of the expression or function of this protein may be useful in the treatment of these cancers or any metastatic cancer.

In addition, the expression of this homolog of Aminopeptidase N is moderate to high in several of the endocrine/metabolic tissues found on this panel, including adipose, liver, pancreas, skeletal muscle and small intestine. Aminopeptidase N (EC 3.4.11.2) is located in the small-intestinal and renal microvillar membranes, and also in other plasma membranes. In the small intestine, aminopeptidase N plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases. Its function in proximal tubular epithelial cells and other cell types is less clear.

Panel 2.2 Summary: Ag1910 The expression of the CG56159-01 gene appears to be highest in a sample derived from a kidney cancer (CT=26.1). In addition, there appears to be substantial expression associated with liver derived tissue, normal colon tissue and a number of normal kidney tissue samples. This is consistent with the expression in Panel 1.3D and the function of this putative protein. (Please see Panel 1.3D for detailed discussion). Thus, the expression of this gene could be used to distinguish this kidney cancer sample from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be of benefit in the treatment of liver cancer, colon cancer or kidney cancer.

Panel 4D Summary: Ag1910/Ag2047 Two experiments with the same probe and primer set produce results that are in excellent agreement, with highest expression of the CG56159-01 gene in the colon (CTs=21-23). This is in concordance with the identification of this gene product as an aminopeptidase N homolog. Recently aminopeptidase N has been implicated in leukocyte chemotaxis and activation. Consistent with this presumed role in the immunologic events of inflammatory and allergic diseases, this gene product is also expressed in a wide range of other cell types of significance in the immune response in health and disease. Thus, significant levels of expression are also seen in treated and untreated lung and dermal fibroblasts and treated and untreated endothelial cells, macrophages and monocytes. The transcript is more highly expressed in resting macrophages and monocytes than in treated cells of these types. Thus, the protein encoded by this transcript may be important in monocytic differentiation and activation and in conditions which involve endothelial cells. Therefore, regulating the expression of this transcript or the function of the protein it encodes could alter the types and levels of monocytic cells regulated by cytokine and chemokine production and T cell activation. Furthermore, antibodies and small molecules that antagonize the function of the this product may reduce or eliminate the symptoms in patients with autoimmune and inflammatory diseases, such as lupus erythematosus, asthma, emphysema, Crohn's disease, ulcerative colitis, arthritis, and psoriasis.

The migration of leukocytes such as neutrophils, monocytes and lymphocytes into inflamed lesions is one of the critical events of inflammation. Although the traditional function of neutrophil-derived antimicrobial proteases is to ingest and kill bacteria, some neutrophil serine proteases have been shown to induce leukocyte migration and activation. Mast cell-derived chymase also has the chemotactic activity for leukocytes. During the acute phase of inflammatory and allergic diseases, the predominantly migrated cells are neutrophils and mast cells, respectively, and in the subsequent chronic phase, monocytes and lymphocytes are mainly migrated. The chemotactic activity for monocytes and lymphocytes of neutrophil-derived serine proteases and mast cell-derived chymase may have a role in switching acute inflammation to chronic inflammation and delayed-type hypersensitivity. Recently, aminopeptidase N and endothelin were shown to induce chemotactic migration of leukocytes. Thus, protease-induced leukocyte chemotaxis and activation may play an important role in immunologic events of inflammatory and allergic diseases.

CNS_neurodegeneration_v1.0 Summary: Ag1952 This panel does not show differential expression of the CG56162-01 gene in Alzheimer's disease. However, this expression profile confirms the presence of this gene in the brain. Please see Panel 1.3D for discussion of this gene in the central nervous system.

Panel 1.3D Summary: Ag1906/Ag2042 The expression of CG56162-01 gene was assessed in two independent runs using 2 different probe/primer pairs, with good concordance between the runs. Highest expression in this panel is seen in brain-derived tissue, including the cerebral cortex and a brain cancer (CTs=25-27). Thus, the expression of this gene could be used to distinguish these samples from other samples in the panel.

This gene encodes a lysophosphase homolog that also has high levels of expression in many of the endocrine/metabolic tissues found on this panel, including adipose, liver, pancreas, pituitary, skeletal muscle and small intestine. Lysophospholipids are detergent-like intermediates in phospholipid metabolism. Lysophospholipases are important enzymes in the regulation of hormone biosynthesis and metabolism, and have been shown to be important in the regulation of insulin secretion (see reference below). Increased lysophospholipids levels have been detected in a variety of diseases including atherosclerosis and hyperlipidemia. In some cases, increased levels of lysophospholipids are hypothesized to result from a dysfunction of lysophospholipids-regulating enzymes including lysophospholipases, which act on biologic membranes to regulate the level of lysophospholipids by hydrolysis. Thus, this gene product may be useful in the treatment of diseases associated with increased lysophospholipids.

This gene also shows high expression in the brain. Lysophospholipases are critical enzymes that regulate brain membrane phospholipids. Alterations in their activity have been associated with a host of neurological disorders, including schizophrenia, Parkinson's disease, and Alzheimer's disease. Thus, therapeutic modulation of the expression or function of this gene or gene product may be useful in the treatment of these diseases. Please note that results from a third experiment with the probe/primer set Ag1952 are not included. The amp plot indicates that there were experimental difficulties with this run.

In order to investigate the mechanism behind fat-induced inhibition of glucose-induced insulin secretion a selection of enzymes that may participate in regulation of pancreatic islet glucose oxidation was studied in islets isolated from mice that had been fed on a laboratory chow diet or on a high-fat diet for 10-12 weeks. At 20 mmol/L glucose production of (14)CO(2) from [U-(14)C]-glucose was decreased 50% in islets from fat-fed mice. At 3.3 mmol/L glucose the glucose oxidation rate was similar in the two groups. The fatinduced decrease in glucose oxidation rate was correlated with a 35% decrease in the maximal glucokinase activity. The K(m) for glucose was unchanged. No differences between the diet groups were found in the activities of hexokinase, phosphofructo-1-kinase, glucose 6-phosphatase or mitochondrial glycerophosphate dehydrogenase. After preincubation with 20 mmol/L glucose the activity of cytosolic Ca(2+)-independent as well as Ca(2+)-dependent phospholipase A(2) was unchanged by fat-feeding. However, the activity of lysophospholipase was significantly increased by fat feeding, which may result in lowered concentrations of islet lysophosphatidyleholine (lysoPC). It is concluded that in fat-induced diabetic animals a decrease in islet glucokinase may contribute considerably to the decrease in islet glucose oxidation rate. Furthermore, the study raises the possibility that changes in islet lysoPC may contribute to the fat-induced attenuation of glucose-induced insulin secretion.

We recently reported that the activity of a calcium-independent subtype of phospholipase A2 is increased in blood of patients with schizophrenia. The present investigation examined whether similar changes take place in brain of patients with this disorder, and for comparison, in patients with bipolar disorder. The activity of two classes of PLA2, calcium-stimulated and independent, were assayed in autopsied temporal, prefrontal and occipital cortices, putamen, hippocampus and thalamus of 10 patients with schizophrenia, 8 patients with bipolar disorder and 12 matched control subjects. Calcium-independent PLA2 activity was increased by 45% in the temporal cortex of patients with schizophrenia as compared with the controls but was not significantly altered in other brain areas. In contrast, calcium-stimulated PLA2 activity was decreased by 27-42% in the temporal and prefrontal cortices and putamen, with no significant alterations in other brain regions. Brain PLA2 activity was normal in patients with bipolar disorder. Calcium-stimulated PLA2 activity was normal in cortex, cerebellum and striatum of rats treated acutely or chronically with haloperidol, whereas calcium-independent PLA2 activity was decreased in striatum of chronically treated animals, indicating that altered PLA2 activity in patients with schizophrenia is unlikely to be a direct effect of medication. Studies of the cellular role played by PLA2 suggest that decreased calcium-stimulated PLA2 activity, as also occurs in striatum of chronic human cocaine users, may be due, in part, to increased dopaminergic activity in the disorder, whereas increased calcium-independent PLA2 activity may be related to abnormal fatty acid metabolism and oxidative stress in schizophrenia.

To determine whether increased oxidative stress in substantia nigra of patients with idiopathic Parkinson's disease might be related to decreased ability of nigral cells to detoxify oxidized membrane phospholipids, we compared levels of the major phospholipid metabolizing enzymes in autopsied substantia nigra with those in non-nigral (n=11) brain areas of the normal human brain. Whereas most enzymes possessed a relatively homogeneous distribution, the activity of the major phospholipid catabolizing enzyme phospholipase A2, assayed in the presence of calcium ions, varied amongst different regions, with substantia nigra possessing the lowest activity. Similarly, calcium-independent phospholipase A2 activity, although possessing a relatively homogeneous regional distribution, was also low in the substantia nigra. This, coupled with low activity of phosphoethanolamine- and phosphocholine-cytidylyltransferases, major regulatory enzymes of phospholipid synthesis, in this brain region, suggest that the rate of phospholipid turnover is low in the substantia nigra. Low activity of key phospholipid catabolic and anabolic enzymes in human substantia nigra might result in reduced ability to repair oxidative membrane damage, as may occur in Parkinson's disease.

Damage to brain membrane phospholipids may play an important role in the pathogenesis of Alzheimer's disease (AD); however, the critical metabolic processes responsible for the generation and repair of membrane phospholipids affected by the disease are unknown. We measured the activity of key phospholipid catabolic and anabolic enzymes in morphologically affected and spared areas of autopsied brain of patients with AD and in matched control subjects. The activity of the major catabolic enzyme phospholipase A2 (PLA2), measured in both the presence and absence of Ca2+, was significantly decreased (−35 to −53%) in parietal and temporal cortices of patients with AD. In contrast, the activities of lysophospholipid acyltransferase, which recycles lysophospholipids into intact phospholipids, and glycerophosphocholine phosphodiesterase, which returns phospholipid catabolites to be used in phospholipid resynthesis, were increased by approximately 50-70% in the same brain areas. Brain activities of enzymes involved in de novo phospholipid synthesis (ethanolamine kinase, choline kinase, choline phosphotransferase, phosphoethanolamine cytidylyltransferase, and phosphocholine cytidylyltransferase) were either normal or only slightly altered. The activities of PLA2 and acyltransferase were normal in the degenerating cerebellum of patients with spinocerebellar atrophy type 1, whereas the activity of glycerophosphocholine phosphodiesterase was reduced, suggesting that the alterations in AD brain were not nonspecific consequences of neurodegeneration. Our data suggest that compensatory phospholipid metabolic changes are present in AD brain that reduce the rate of phospholipid loss via both decreased catabolism (PLA2) and increased phospholipid resynthesis (acyltransferase and glycerophosphocholine phosphodiesterase).

Panel 2.2 Summary: Ag1906 The expression of the CG56162-01 gene appears to be highest in a sample derived from normal kidney tissue (CT=28.1). In addition, there is substantial expression associated with kidney cancer tissue, liver cancer tissue, breast cancer tissue and colon cancer tissue. Thus, the expression of this gene could be used to distinguish this normal kidney tissue sample from other samples in the panel. Moreover, therapeutic modulation of thie gene, through the use of antibodies, small molecule drugs or protein therapeutics might be beneficial in the treatment of kidney cancer, liver cancer, breast cancer or colon cancer.

Panel 2D Summary: Ag1952 The expression of the CG56162-01 gene appears to be highest in a sample derived from kidney cancer tissue (CT=26.1). In addition, there is substantial expression associated with other samples of kidney cancer tissue, liver cancer tissue, breast cancer tissue, colon cancer tissue, normal prostate and normal lung. Thus, the expression of this gene could be used to distinguish this kidney cancer tissue sample from other samples in the panel. Moreover, therapeutic modulation of thie gene, through the use of antibodies, small molecule drugs or protein therapeutics might be beneficial in the treatment of kidney cancer, liver cancer, breast cancer or colon cancer.

Panel 4D Summary: Ag1906/Ag1952/Ag2042 The expression of CG56162-01 gene was assessed in three independent runs using three different probe/primer pairs, with good concordance between the runs. This gene is expressed at moderate levels in a wide variety of cells including resting macrophages, TNF-alpha-activated dermal fibroblasts, LPS-stimulated dendritic cells, TNF-alpha+IL-1-beta-activated pulmonary artery endothelial cells, TNF-alpha+IL-1-beta-activated lung microvascular cells, and TNF-alpha+IFN-gamma-activated umbilical vein endothelial cells. Thus, sntibodies and small molecules that antagonize the function of the CG120803-01 geein product may be useful to reduce or eliminate the symptoms in patients with inflammatory and autoimmune diseases, such as lupus erythematosus, asthma, emphysema, Crohn's disease, ulcerative colitis, multiple sclerosis, rheumatoid arthritis, osteoarthritis, and psoriasis.

CNS_neurodegeneration_v1.0 Summary: Ag1677 No change of expression of the CG56164-01 gene is noted in Alzheimer's disease, consistent with the scientific literature. However, this panel does confirm expression of this gene in the brain. Please see Panel 1.3D for discussion of utility of this gene in the central nervous system.

In Down syndrome (DS) as well as in Alzheimer's disease (AD) oligodendroglial and myelin alterations have been reported. 2′,3′-cyclic nucleotide-3′-phosphodiesterase (CNPase) and carbonic anhydrase II (CA II) are widely accepted as markers for oligodendroglia and myelin. However, only data on CNPase activity have been available in AD and DS brains so far. In our study we determined the protein levels of CNPase and CA II in DS, AD and in control post mortem brain samples in order to assess oligodendroglia and myelin alterations in both diseases. We used two dimensional electrophoresis to separate brain proteins that were subsequently identified by matrix assisted laser desorption and ionization mass-spectroscopy (MALDI-MS). Seven brain areas were investigated (frontal, temporal, occipital and parietal cortex, cerebellum, thalamus and caudate nucleus). In comparison to control brains we detected significantly decreased CNPase protein levels in frontal and temporal cortex of DS patients. The level of CA II protein in DS was unchanged in comparison to controls. In AD brains levels of CNPase were decreased in frontal cortex only. The level of CA II in all brain areas in AD group was comparable to controls. Changes of CNPase protein levels in DS and AD are in agreement with the previous finding of decreased CNPase activity in DS and AD brain. They probably reflect decreased oligodendroglial density and/or reduced myelination. These can be secondary to disturbances in axon/oligodendroglial communication due to neuronal loss present in both diseases. Alternatively, reduced CNPase levels in DS brains may be caused by impairment of glucose metabolism and/or alterations of thyroid functions.

General_screening_panel_v1.4 Summary: Ag1677 Highest expression of the CG56164-01 gene in this panel is seen in the cerebellum (CT=26.2), with expression also seen across all brain areas represented in this panel. This expression profile is consistent with the brain expression seen in the CNS_neurodegeneration_v1.0 panel. Please see Panel 1.3D for discussion of utility of this gene in the central nervous system.

Overall, this gene is expressed mostly in normal tissues, with much lower expression in most cancer cell lines. This suggests that loss of expression of this gene might be required for the proliferation of these cancer cell lines. A moderate level of expression is seen in a lung cancer and two breast cancer cell lines. Thus, the loss of expression might be used as a diagnostic marker for most cancers, except the cancer tissues from which the lung and breast cancer cell lines were derived. In addition, the protein product of this gene might be of use in the treatment of these cancers.

This gene is also moderately expressed in a wide variety of metabolic tissues including pancreas, adrenal, thyroid, pituitary adult and fetal heart, adult and fetal skeletal muscle, adult and fetal liver, and adipose. Carbonic anhydrase III is reduced in adipose tissue in several animal models of genetic obesity. Thus, an activator of this gene product could potentially be a drug treatment for the prevention and/or treatment of obesity in humans.

In addition, this gene is expressed at higher levels in fetal lung (CT=26.5) than in adult lung (CT=31.3). Thus, expression of this gene could be used to differentiate between fetal and adult lung tissue. The expression of this gene at significant levels in the lung is consistent with published reports (see references below.) This suggests that the gene product is involved in the homeostasis of the lung. Therefore, therapeutic modulation of the expression or function of the protein encoded by this gene could be effective in treating disease that affect the lung or its function.

New Zealand obese (NZO) mouse, a genetic model of obesity, shows hyperphagia, hyperinsulinemia and leptin resistance. We analyzed subcutaneous adipose tissue proteins in NZO mice with a two-dimensional gel electrophoresis technique followed by protein sequence analysis. NZO mice showed hyperinsulinemia and hyperleptinemia. Abdominal subcutaneous adipose tissue was inspected in NZO and C57BL/6J lean mice. Two-dimensional gel electrophoresis detected 4 spots which were obviously reduced in NZO mice. Those spots were p26, p19, p18 and p15. Internal sequences of the p26 and p15 protein were homologous with those of carbonic anhydrase III, p19 was cytochrome b5, p18 was superoxide dismutase. Serum arachidonic acid level in NZO mice was lower by 80% of C57BL/6J mice. The present study demonstrated the reduction of several enzymes related to lipid metabolism in NZO mice. These data raises the hypothesis that the supposed changes of membrane fluidity caused by altered membrane lipid content may involve central leptin resistance of this model of obesity.

To achieve a better understanding of the biochemical basis of obesity, we have undertaken comparative analyses of adipose tissue of lean and obese mice. By two-dimensional gel analysis, carbonic anhydrase-III (CA III) has been identified as a major constituent of murine adipose tissue. Quantitative comparisons of CA III protein and mRNA levels indicate that this enzyme is expressed at lower levels in adipose tissue from animals that were either genetically obese or had experimentally induced obesity compared to levels in the corresponding lean controls. This decrease in CA III expression was unique to adipose tissue, since other CA III-containing organs and tissues did not show a change when lean and obese animals were compared. Additionally, levels of CA III in adipose tissue from obese animals responded to acute changes in energy balance of the animal. These results are discussed in light of possible metabolic roles for CA III.

Panel 1.3D Summary: Ag1677 The expression of the CG56164-01 gene was assessed in two independent runs on this panel and there appears to be good concordance between runs. This gene is expressed mostly innormal tissues, with much lower expression in most cancer cell lines. Highest expression of the gene in this panel is seen in the lung (CTs=28). This significant expression in the lung is consistent with the results in General_screening_panel_v1.4 and suggests that this gene product is involved in the homeostasis of this organ. The higher association of this gene with normal tissues suggests that loss of expression of this gene might be required for the proliferation of the cancer cell lines in this panel. Thus, this loss of expression might be used as a diagnostic marker for cancer.

As in the previous panel, this gene is widely expressed in a variety of metabolic tissues including pancreas, adrenal, thyroid, pituitary, adult and fetal heart, adult and fetal skeletal muscle, and adipose. Thus, this gene product may be a small molecule target for the treatment of metabolic disease, including Types 1 and 2 diabetes.

This gene encodes a homolog of carbonic anhydrase which is a known marker for oligodendroglia. Carbonic anhydrase expression in the brain is useful for distinguishing between neurons and oligodendrogylia. Thus, this gene product may utility in monitoring the progression of diseases that involve the myelinating function of oligodendroglia, such as Multiple Sclerosis and Alzheimer's disease.

Panel 2D Summary: Ag1677 As in the previous panels, expression of the CG56164-01 gene is more highly associated with normal tissues. Highest expression of the gene in this panel is seen in a normal colon sample (CT=27.8). Furthermore, expression of this gene is higher in normal colon, stomach, ovary, thyroid, kidney and lung than in the corresponding adjacent tumor tissues. Thus, the loss of expression of this gene could be used to distinguish malignant colon, lung, stomach, ovary, thyroid and kidney tissue from normal tissue from these organs. In addition, the protein product of this gene might be of use in the treatment of these cancers.

Panel 4D Summary: Ag1677 The CG55936-01 transcript is expressed at low but significant levels in the thymus, lung and kidney (CTs=30-35), again showing preferential expression in normal tissues. Thus, this gene or the protein it encodes could be used to detect these tissues. Therapeutically, the protein encoded for by this transcript could be used for immune modulation by regulating T cell development in the thymus.

Panel 1.2 Summary: Ag819 The expression of the CG55117-01 gene was assessed in two independent runs in panel 1.2 with excellent concordance between the runs. The expression of this gene appears to be highest in a colon cancer cell line (CaCo-2)(CTs=25). In addition, there appears to be substantial expression in colon cancer cell lines and ovarian cancer cell lines. Thus, the expression of this gene could be used to distinguish the CaCo-2 derived sample from other samples in the panel.

Among tissues with metabolic function, this gene has moderate levels of expression in adrenal, thyroid, pituitary, skeletal muscle, and adult and fetal liver. It is highly expressed in pancreas (CT value=26). Although this gene has no reported dysregulation in metabolic disease, it may be a monoclonal antibody target for the treatment of diseases of the metabolic-endocrine axis, including obesity and Types 1 and 2 diabetes. In addition, this gene appears to be differentially expressed in adult (CT value=28) vs fetal heart (CT value=32-33), and may be useful for the identification of the adult phenotype in this tissue.

This gene also shows moderate expression in all CNS regions examined. However, its expression in the fetal brain is considerably higher (greater than 10-fold) suggesting a role in neurodevelopment. Prominin is believed to play a role in the formation of lipid membrane protrusions, their lipid content and membrane to membrane interactions, all critical for synapse formation. The expression of this gene in the developing brain supports a role in synaptogenesis for this molecule. Compensatory synaptogenesis has been shown to occur in the adult brain, especially in response to brain injury or neuronal loss. Therefore, therapeutic modulation of this gene or its protein product may be of therapeutic benefit in clinical conditions where an increase in compensatory synaptogenesis is desirable including stroke, head trauma, spinal cord trauma, Alzheimer's, Parkinson's or Huntington's diseases, multiple sclerosis, or ALS.

Prominin is the first identified member of a novel family of polytopic membrane proteins conserved throughout the animal kingdom. It has an unusual membrane topology, containing five transmembrane domains and two large glycosylated extracellular loops. In mammals, prominin is expressed in various embryonic and adult epithelial cells, as well as in nonepithelial cells, such as hematopoietic stem cells. At the subcellular level, prominin is selectively localized in microvilli and other plasma membrane protrusions, irrespective of cell type. At the molecular level, promrinin specifically interacts with membrane cholesterol and is a marker of a novel type of cholesterol-based lipid ‘raft’. A frameshift mutation in the human prominin gene, which results in a truncated protein that is no longer transported to the cell surface, is associated with retinal degeneration. Given that prominin is concentrated in the plasma membrane evaginations at the base of the outer segment of rod photoreceptor cells, which are essential precursor structures in the biogenesis of photoreceptive disks, it is proposed that prominin has a role in the generation of plasma membrane protrusions, their lipid composition and organization and their membrane-to-membrane interactions.

Panel 2D Summary: Ag819 The expression of the CG55117-01 gene was assessed in two independent runs in panel 2D with the runs showing excellent concordance. The expression of this gene is found to be highest in samples derived from an ovarian cancer and a lung cancer (CTs=26). In addition, there is substantial expression seen in other cancer samples including a kidney cancer, two colon cancers and two gastric cancers. Thus, the expression of this gene could be used to distinguish the ovarian or lung cancer from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be of benefit in the treatment of ovarian, lung, kidney, colon or gastric cancers.

Panel 3D Summary: Ag819 The expression of the CG55117-01 gene is highest in a sample derived from a brain cancer (medulloblastoma) derived cell line (D283 cells)(CT=28.3). In addition, there is substantial expression seen in several lung cancer cell lines, a gastric cancer cell line and several pancreatic cancer cell lines. Thus, the expression of this gene could be used to distinguish D283 cells from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be of benefit in the treatment of lung, brain, pancreatic or gastric cancers.

Panel 4D Summary: Ag819 The CG55117-01 gene, which encodes a 5-transmembrane protein, human haematopoietic progenitor cell antigen AC133 homolog is expressed at moderate levels in thymus, colon, and lupus kidney. Therefore, antibodies and small molecule drugs that antagonize the function of the CG55117-01 gene product may reduce or eliminate the symptoms in patients with luplus nephritis.

Panel 5 Islet Summary: Ag819 The CG55117-01 gene has low levels of expression in placenta and islets (CTs=32-34). Thus, expression of this gene could be used to differentiate samples derived from these tissues from other samples on this panel.

CNS_neurodegeneration_v1.0 Summary: Ag2256 Expression of the CG55690-01 gene is not differentially expressed in Alzheimer's disease, based on the expression in this panel. However, these results confirm expression of this gene in the brain. Please see General_screening_panel_v1.5 for discussion of utility of this gene in the central nervous system.

General_screening_panel_v1.5 Summary: Ag2256/Ag4933 Two experiments with the same probe and primer set show highest expression of the CG55690-01 gene in a sample derived from a lung cancer cell line (NCI-H146) (CTs=30). In addition, there are a number of lung cancer cell lines expressing this gene as well as colon cancer and ovarian cancer cell lines. Thus, the expression of this gene could be used to distinguish NCI-H146 cells from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be of benefit in the treatment of lung cancer, colon cancer or ovarian cancer.

This gene also has moderate expression in adipose, adult and fetal skeletal muscle, and pituitary. Although this gene product has no reported associations with metabolic disease/metabolism, its expression profile suggests that it may be a monoclonal antibody target for the treatment of metabolic and endocrine disease, including obesity and Types 1 and 2 diabetes.

In addition, this gene is expressed at low levels in all CNS regions examined. This gene is a homolog of Frizzled. Frizzled genes play a role in cell fate determination. Therefore, this gene may be of use in stem cell research and therapy, specifically to control the differentiation of stem cells into post-mitotic neurons.

Frizzled genes, encoding WNT receptors. play key roles in cell fate determination. Here, we isolated two Xenopus frizzled genes (Xfz10A and Xfz10B), probably reflecting pseudotetraploidy in Xenopus. Xfz10A (586 amino acids) and Xfz10B (580 amino acids) both encoded by a single exon, consisted of the N-terminal cysteine-rich domain, seven transmembrane domains, and the C-terminal Ser/Thr-X-Val motif. Xfz10A and Xfz10B were 97.0% identical at the amino acid level, and Xfz10B was 100% identical to previously reported Xfz9, yet Xfz10A was 85.3% and 62.4% identical to FZD10 and FZD9, respectively. Xfz10 mRNA appeared as 3.4 kb in adult tissues and embryos. RT-PCR analyses revealed the expression of more Xfz10A mRNA in stomach, kidney, eye, skeletal muscle, and skin, and more Xfz10B mRNA in heart and ovary, but in embryos, two mRNAs were equally expressed from the blastula stage with their peak expression at the late gastrula stage. The main site of Xfz10 mRNA expression was neural fold at the neurula stage and the dorsal region of midbrain, hindbrain, and spinal cord at the tadpole stage. These results suggest that Xfz10 has important roles in neural tissue formation.

Panel 1.3D Summary: Ag2256 Two experiments with the same probe and primer set show highest expression of the CG55690-01 gene in fetal skeletal muscle (CTs=31-33). This gene is expressed at much higher levels in fetal skeletal muscle than in adult skeletal muscle (CTs=36-37). Therefore, expression of this gene could be used to differentiate between adult and fetal skeletal muscle. In addition, the higher levels of expression in fetal skeletal muscle suggest that the protein product may enhance muscular growth or development in the fetus and thus may also act in a regenerative capacity in the adult. Therefore, therapeutic modulation of the protein encoded by this gene could be useful in treatment of muscle related diseases. More specifically, treatment of weak or dystrophic muscle with the protein encoded by this gene could restore muscle mass or function.

This panel also shows expression of this gene in the CNS. Please see General Screening Panel 1.5 for a discussion of utility of this gene in the central nervous system.

Panel 2D Summary: Ag2256 The expression of the CG55690-01 gene was assessed in two independent runs in panel 2D with excellent concordance between runs. The expression of this gene is found to be highest in a sample derived from a lung cancer (CTs=30). In addition, other lung cancers were found to express this gene, while their normal adjacent tissue counterparts were low to undetectable for the expression of this gene. This expression is consistent with the expression seen in General_screening_panel_v1.5. Thus, the expression of this gene could be used to distinguish lung cancer samples from other samples in the panel and, in particular, normal adjacent lung tissue. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial in the treatment of lung cancer.

Panel 3D Summary: Ag2256 The expression of the CG55690-01 gene appears to be highest in a sample derived from a lung cancer cell line (NCI-H146)(CT=30). In addition, there is a cluster of lung cancer cell lines that appear to be expressing this gene, consistent with expression seen in previous panels. Thus, the expression of this gene could be used to distinguish NCI-H146 cells from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics might be beneficial in the treatment of lung cancer.

Panels 4.1D and 4D Summary: Ag4933 The CG55690-01 gene, a frizzled 9 homolog, is expressed at moderate levels in kidney (CT=31.31) and thymus (CT=32.69). Expression was analyzed independently with panel 4D and found to be at low levels in colon (CT=33.55) and lung (CT=34.7). Therefore, antibodies or small molecule antagonists that block the function of the CG55690-01 product may be useful to reduce or eliminate the symptoms in patients with diseases of kidney, thymus, colon, and lung.

Panel 5 Islet Summary: Ag2256 Expression of the CG55690-01 gene is low/undetectable in all samples on this panel (CTs>35). (Data not shown.)

Panel 1.3D Summary: Ag2169 The expression of the CG56008-01 gene was assessed in two independent runs in panel 1.3D with excellent concordance. The expression of this gene is highest in a sample derived from a breast cancer cell line (MCF-7)(CTs=25-26). Thus, the expression of this gene could be used to distinguish MCF-7 cells from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics may be beneficial in the treatment of breast cancer.

This tissue is moderately expressed in a variety of metabolic tissues, including pancreas, adrenal, thyroid, pituitary, adult and fetal heart, fetal liver and adipose.

Thus, this gene product may be a monoclonal antibody target for the treatment of metabolic and endocrine disease, including obesity and Types 1 and 2 diabetes. As a putative zinc transporter, this gene may also be a potential target for the enhancement of insulin secretion and sensitivity in all forms of Type 2 diabetes. In addition, this gene is differentially expressed in fetal (CTs=31-32) vs adult skeletal muscle (CTs=34-35), and may be useful for the identification of the fetal source of this tissue. Furthermore, the relative overexpression of this gene in fetal skeletal muscle suggests that the protein product may enhance muscular growth or development in the fetus and thus may also act in a regenerative capacity in the adult. Therefore, therapeutic modulation of the protein encoded by this gene could be useful in treatment of muscle related diseases. More specifically, treatment of weak or dystrophic muscle with the protein encoded by this gene could restore muscle mass or function.

Among tissues of CNS origin, this gene is expressed at moderate levels in all regions examined. This gene, a LIV-1 homolog, may be involved in zinc homeostasis. Zinc is critical to brain functions as it may serve as an endogenous neuromodulator in synaptic neurotransmission. Thus, this gene would be a drug target for the treatment of learning deficiencies and seizure disorders associated with improper zinc trafficking.

Zinc has insulin-like effects on cells, including promotion of both lipogenesis and glucose transport. The relationship between zinc and the stimulation of glucose transport is unclear.

We hypothesize that zinc affects the insulin-signaling pathway. In this study, the effect of zinc on glucose transport and insulin signaling was examined in 3T3-L1-preadipocytes and -adipocytes. Treatment of cells with up to 200 micromol/L zinc significantly increased glucose transport (P<0.05). The effect of zinc on adipocytes was greater than on preadipocytes, and the effect of zinc plus insulin was greater than that of either insulin or zinc alone. Cytochalasin D, which disrupts actin filaments., attenuated the increase of glucose transport induced by zinc or insulin (P<0.05). At 100 nmol/L, wortmannin, the phosphoinositide (PI) 3-kinase inhibitor, decreased basal glucose transport and blocked zinc-stimulated glucose transport in both cell types (P<0.05). H7, an inhibitor of protein kinase C, did not reduce basal glucose transport but decreased zinc-induced glucose transport (P<0.05). Zinc increased tyrosine phosphorylation of the insulin receptor beta subunit of both preadipocytes and adipocytes after 5-10 min of treatment (P<0.05). Zinc at 200 micromol/L did not affect tyrosine phosphorylation of insulin receptor substrate (IRS)-1 or -2; further, there was no effect of zinc on the association of the p85 subunit of PI 3-kinase and IRS-1. Zinc significantly increased serine-473 phosphorylation of At in both preadipocytes and adipocytes (P ] 0.05). The PI 3-kinase inhibitor, wortmannin, totally blocked the effect of zinc on Akt activation. Hence, it appears that zinc can induce an increase in glucose transport into cells and potentiate insulin-induced glucose transport, likely acting through the insulin-signaling pathway.

Taylor KM. LIV-1 breast cancer protein belongs to new family of histidine-rich membrane proteins with potential to control intracellular Zn2+ homeostasis. IUBMB Life 2000 April; 49(4):249-53

Investigation of the protein product of the oestrogen-regulated gene LIV-1, implicated in metastatic breast cancer, has revealed 10 protein sequences of unknown function that belong to a new family with potential to control intracellular Zn2+ homeostasis. Sequence alignment highlights the similarity in transmembrane domains and extramembrane charged residues, indicating potential ion-transport ability. This family has a novel highly conserved motif of 66 residues, including a transmembrane domain and a catalytic zinc-binding sequence of zinc metalloproteases, containing conserved (indicated in bold type) proline and glutamine residues, HEXPHEXGD. These proteins contain more plentiful histidine-rich repeats than zinc transporters, suggesting an ability to bind or transport zinc across membranes. I propose that these 11 proteins form a new family with the potential to control intracellular Zn2+ homeostasis.

Zinc, an essential nutrient, is supplied to the brain via both the blood-brain and blood-cerebrospinal fluid barriers. Zinc is most concentrated in the limbic system, i.e. the hippocampus and amygdala, zinc-containing glutaminergic neuron-rich areas. A large portion of zinc serves the function of zinc metalloproteins in neurons and glial cells. In zinc-containing glutaminergic neurons, vesicular zinc, probably ionic zinc, may serve as an endogenous neuromodulator in synaptic neurotransmission. Vesicular zinc is dynamically coupled to the electrophysiological activity of zinc-containing glutaminergic neurons. Dietary zinc deprivation may influence zinc homeostasis in the brain, resulting in brain dysfunction such as learning impairment. Excessive excitation of zinc-containing glutaminergic neurons causes a decrease in vesicular zinc, and the decrease might be associated with the susceptibility to seizure. Alteration of zinc levels released into the synaptic cleft may influence neurotransmission in zinc-containing glutaminergic synapses. Therefore, zinc homeostasis in the presynaptic vesicle is important for the function of zinc-containing glutaminergic neurons

Panel 2D Summary: Ag2169 The expression of the CG56008-01 gene was assessed in two independent runs in panel 2D with excellent concordance. It appears that the expression of this gene is highest in a sample derived from a breast cancer (CTs=23-24), consistent with expression in Panel 1.3D. In addition, there is a strong cluster of breast cancers expressing this gene, while expression of this gene in other tissues is almost absent, with the exception of a cluster of prostate derived samples. Thus, the expression of this gene could be used to distinguish breast cancer samples from the other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics may be beneficial in the treatment of breast cancer.

Panel 3D Summary: Ag2169

The expression of the CG56008-01 gene appears to be highest is a sample derived from a lung cancer cell line (DMS 79)(CT=27.8). In addition, there appears to be significant levels of expression in a cluster of other lung cancer cell lines. Thus, the expression of this gene could be used to distinguish DMS 79 cells from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, antibodies or protein therapeutics may be beneficial in the treatment of lung cancer.

Panel 4D Summary: Ag2169 Two experiments with the same probe and primer set show highest expression of the CG56008-01 gene, a LIV-1 homolog in small airway epithelium stimulated with TNF-alpha and IL-1beta (CTs=27). Moderate levels of expression are also seen in pokeweed mitogen-activated peripheral blood mononuclear cells (mainly B cells), ionomycin-activated Ramos B cell, pokeweed mitogen-activated purified peripheral blood B lymphocytes, B lymphocytes activated with CD40L and IL-4, and a number of cytokine-activated and resting cells including NCI-H292 pulmonary mucoepidermoid epithelial cells, lung fibroblasts, and dermal fibroblasts. Based on these levels of expression in cytokine-activated B cells and cells in lung and skin, small molecule antagonists that block the function of this gene product may be usefull as therapeutics that reduce or eliminate the symptoms in patients with autoimmune and inflammatory diseases in which activated B cells present antigens in the generation of the aberrant immune response, including Crohn's disease, ulcerative colitis, multiple sclerosis, chronic obstructive pulmonary disease, asthma, emphysema, rheumatoid arthritis., or psoriasis.

Panel 1.2 Summary: Ag1437 The expression of the CG56006-01 gene appears to be highest in a sample derived from normal adult kidney tissue (CT=23.3). In addition, there is substantial expression in samples derived from liver tissue. Of note is the difference in expression of this gene between adult and fetal kidney (CT=29) tissue. Thus, the expression of this gene could be used to distinguish normal kidney tissue from other samples in the panel, and in particular, from fetal kidney tissue.

There are also moderate to high levels of expression of this putative hepsin in a number of endocrine/metabolic related tissues including adrenal GI tract, kidney, liver, pancreas and skeletal muscle and thyroid. Therefore, a therapeutic modulator to this gene and/or gene product may prove useful in the treatment of diseases where these tissues are involved.

Panel 1.3D Summary: Ag1437 The expression of the CG56006-01 gene was assessed in two independent runs on panel 1.3D with excellent concordance between runs. The expression of this gene appears to be highest in samples derived from liver tissue. In addition, there is substantial expression associated with normal kidney, bladder, stomach and pancreas tissue. There is also substantial expression associated with cell lines derived from liver cancer, breast cancer and colon cancer. Thus, the expression of this gene could be used to distinguish liver derived samples from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies may be useful in the treatment of colon cancer, breast cancer or liver cancer.

In addition, this gene is expressed at much higher levels in fetal (CTs=33) when compared to adult skeletal muscle (CTs=36-40). This observation suggests that expression of this gene can be used to distinguish fetal from adult skeletal muscle. In addition, the relative overexpression of this gene in fetal skeletal muscle suggests that the protein product may enhance muscular growth or development in the fetus and thus may also act in a regenerative capacity in the adult. Therefore, therapeutic modulation of the protein encoded by this gene could be usefull in treatment of muscle related diseases. More specifically, treatment of weak or dystrophic muscle with the protein encoded by this gene could restore muscle mass or function.

Panel 2D Summary: Ag1437 The expression of the CG56006-01 gene was assessed in two independent runs on panel 2D with excellent concordance between runs. The expression of this gene appears to be highest in samples derived from liver tissue, in particular malignant liver. This expression is consistent with the expression seen in Panel 1.3D. In addition there is substantial expression associated with normal kidney tissues, when compared to their malignant counterparts, and breast and prostate cancers. Thus, the expression of this gene could be used to distinguish liver derived samples from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies may be useful in the treatment of liver cancer, kidney cancer, breast cancer or prostate cancer.

Prostate cancer is the most commonly diagnosed noncutaneous cancer in men. Despite this fact, many of the genetic changes that coincide with prostate cancer progression remain enigmatic. We have addressed this problem by characterizing the expression profiles of several benign and malignant human prostate samples, and we have identified several genes that are differentially expressed between benign and malignant glands. One gene that was overexpressed encodes the serine protease hepsin. We used an independent sample set to confirm that hepsin is overexpressed in prostate tumors, and in situ hybridization demonstrates that hepsin is specifically overexpressed in the carcinoma cells themselves. These facts, together with the molecular properties of hepsin, make it an ideal target for prostate cancer therapy.

Panel 4D Summary: Ag1437 The CG56006-01 transcript is expressed almost exclusively in activated monocytes at low but significant levels. This transcript encodes a serine protease hepsin, a transmembrane protease which has implicated in cell growth and maintenance. The expression of this transcript in LPS treated monocytes, cells that play a crucial role in linking innate immunity to adaptive immunity, suggests a role for this gene product in initiating inflammatory reactions. Therefore, modulation of the expression or activity of this gene through the application of monoclonal antibodies may reduce or prevent early stages of inflammation and reduce the severity of inflammatory diseases such as psoriasis, asthma, inflammatory bowel disease, rheumatoid arthritis, osteoarthritis and other lung inflammatory diseases.

Panel 1.3D Summary: Ag1672/Ag1673 Two experiments with the same probe and primer set produce results that are in excellent agreement with highest expression of the CG56149-01 gene in a gastric cancer cell line (NCI-N87) or a brain cancer cell line (U-118-MG)(CTs=26-27). Thus, the expression of this gene could be used to distinguish these samples from other samples in the panel.

This gene encodes a protein that is homologous to nardilysin, an N-arginine (R) dibasic (NRD) convertase metalloendopeptidase of the M16 family, that specifically cleaves peptide substrates at the N-terminus of arginines in dibasic motifs in vitro. The peptidase M16 family is also known as the insulinase family and nardilysin is the closest homolog of the insulin degrading enzyme, insulinase. The ability of nardilysin to degrade insulin has not been proven. However, the high levels of expression in metabolic tissues in this panel, including adipose, fetal and adult skeletal muscle, pancreas, adrenal, thyroid and pituitary glands suggest that this gene product may have a profound effect on limiting the degradation of insulin in tissues relevant to type II diabetes (e.g. adipose, skeletal muscle).

There is also a significant level of difference between expression in adult(CTs=31-40) and fetal liver tissue(CTs=28), making this gene and/or gene-product a good candidate for distinguishing both forms. A putative role for this gene-product is in the post-translational processing of bioactive peptides from their inactive precursors.

This gene is also highly expressed in the testis. Nardilysis has been implicated in sperniogenesis. Thus, expression of this gene could be used as a marker for testis tissue. Furthermore, therapeutic modulation of the expression or function of this gene may be useful in the treatment of male reproductive disorders. A third experiment with the probe and primer set Ag3263 shows low/undetectable levels of expression in all the samples on this panel. (CTs>35). (Data not shown.)

N-arginine (R) dibasic (NRD) convertase (nardilysin; EC 3.4.24.61), a metalloendopeptidase of the M16 family, specifically cleaves peptide substrates at the N-terminus of arginines in dibasic motifs in vitro. In rat testis, the enzyme localizes within the cytoplasm of spermatids and associates with microtubules of the manchette and axoneme. NRD1 and NRD2 convertases, two NRD convertase isoforms, differ by the absence (isoform 1) or presence (isoform 2) of a 68-amino acid insertion close to the active site. In this study, we overexpressed both isoforms, either by vaccinia virus infection of BSC40 cells or transfection of COS-7 cells. The partially purified enzymes exhibit very similar biochemical and enzymic properties. Microsequencing revealed that NRD convertase is N-terminally processed. Results of immunocytofluorescence, immunoelectron microscopy and subcellular fractionation studies argue in favour of a primary cytosolic localization of both peptidases. Although the putative signal peptide did not direct NRD convertase into microsomes in an in vitro translation assay, biotinylation experiments clearly showed the presence of both isoforms at the cell surface. In conclusion although most known processing events at pairs of basic residues are achieved by proprotein convertases within the secretory pathway, NRD convertase may fulfil a similar function in the cytoplasm and/or at the cell surface.

Rat testis NRD convertase (EC 3.4.24.61) is a Zn2+dependent endopeptidase that cleaves, in vitro, peptide substrates at the N-terminus of Arg residues in dibasic sites. This putative processing enzyme of the insulinase family of metallopeptidases exhibits a significant degree of similarity to insulinase and two yeast processing enzymes, Axl1 and Ste23. We report the cloning of two human testis cDNA species encoding isoforms of NRD convertase, hNRD1 and hNRD2. Whereas the hNRD1 transcript (3.7 kb) is equivalent to the previously characterized rat cDNA (rNRD1), hNRD2 and rNRD2 are 3.9 kb novel forms containing a nucleotide insertion encoding a 68-residue segment. This motif, which is inserted N-terminal of the Zn2+binding site, HXXEH, is contained within the most conserved region among the insulinase family members. Analysis of the deduced primary sequences revealed 92% identity between rat and human orthologues. The human gene encoding NRD convertase was localized to chromosome 1p32.1-p32.2. Whereas NRD convertase is mostly expressed in testis and in 24 cell lines, low mRNA levels were detected in most of the 27 other tissues tested.

J Cell Sci 1996 November; 109 (Pt 11):2737-45

N-arginine dibasic convertase is a novel metalloendopeptidase which selectively cleaves at the N terminus of arginine residues in paired basic amino acids. Although present in brain and several other tissues, NRD convertase is particularly abundant in testis, where its expression appeared to be restricted to germ cells. Low levels of both mRNA and its corresponding protein were detected early in spermatogenesis. However, a marked accumulation of the protein was observed during late steps (14 to 19) of spermiogenesis. By electron microscopy, the NRD convertase immunoreactivity was localized in the cytoplasm of elongating and elongated spermatids, with a noticeable concentration at the level of two microtubular structures, i.e. the manchette and the axoneme. These observations strongly support the hypothesis that NRD convertase is involved in processing events potentially associated with the morphological transformations occurring during spermiogenesis.

General_screening_panel_v1.4 Summary: Ag1681 The CG56151-01 gene, a glucose transporter type 2 homolog, is predominantly expressed in liver. GLUT2 facilitates the transport of glucose into the liver. This gene is also expressed in brain, pancreas, and testis. This is consistent with immunocytochemistry data that shows that the Glut2 gene is expressed in insulin producing beta cells in the pancreas and aids in regulation of insulin secretion. Since the liver is responsible for gluconeogenesis, enhancing glucose uptake through GLUT2 may produce a negative feedback loop that would decrease hepatic glucose production. This could result in a lowering of blood glucose, a major therapeutic goal for the treatment of Type II (non-insulin dependent) diabetes. Thus, enhancing the function of the protein encoded by the CG56151-01 gene with an agonist antibody therapeutic could restore balance to blood glucose levels in patients with Type II diabetes.

In addition, this gene is expressed at higher levels in fetal liver and lung (CTs=29) than in the adult sources of these tissues. Thus, expression of this gene could be used to differentiate between the two sources of these tissues.

The high Km glucose transporter GLUT2 is a membrane protein expressed in tissues involved in maintaining glucose homeostasis, and in cells where glucose-sensing is necessary. In many experimental models of diabetes, GLUT2 gene expression is decreased in pancreatic beta-cells, which could lead to a loss of glucose-induced insulin secretion. In order to identify factors involved in pancreatic beta-cell specific expression of GLUT2, we have recently cloned the murine GLUT2 promoter and identified cis-elements within the 338-bp of the proximal promoter capable of binding islet-specific trans-acting factors. Furthermore, in transient transfection studies, this 338-bp fragment could efficiently drive the expression of the chloramphenicol acetyl transferase (CAT) gene in cell lines derived from the endocrine pancreas, but displayed no promoter activity in non-pancreatic cells. In this report, we tested the cell-specific expression of a CAT reporter gene driven by a short (338 bp) and a larger (1311 bp) fragment of the GLUT2 promoter in transgenic mice. We generated ten transgenic lines that integrated one of the constructs. CAT mRNA expression in transgenic tissues was assessed using the RNAse protection assay and the quantitative reverse transcribed polymerase chain reaction (RT-PCR). Overall CAT mRNA expression for both constructs was low compared to endogenous GLUT2 mRNA levels but the reporter transcript could be detected in all animals in the pancreatic islets and the liver, and in a few transgenic lines in the kidney and the small intestine. The CAT protein was also present in Langerhans islets and in the liver for both constructs by immunocytochemistry. These findings suggest that the proximal 338 bp of the murine GLUT2 promoter contain cis-elements required for the islet-specific expression of GLUT2.

Panel 1.3D Summary: Ag1681 Expression of the CG56151-01 gene is restricted to liver derived tissue an important metabolic tissue, in this panel (CTs=27). This liver specific expression is consistent with expression in other panels and with published data (see reference below.) Thus, expression of this gene could be used as a marker for liver tissue. This gene encodes a glut2 homolog. Please see General_screening_panel_panel_v1.4 for discussion of utility of this gene in metabolic disease.

Previous studies have shown that glucose increases the glucose transporter (GLUT2) mRNA expression in the liver in vivo and in vitro. Here we report an analysis of the effects of glucose metabolism on GLUT2 gene expression. GLUT2 mRNA accumulation by glucose was not due to stabilization of its transcript but rather was a direct effect on gene transcription. A proximal fragment of the 5′ regulatory region of the mouse GLUT2 gene linked to a reporter gene was transiently transfected into liver GLUT2-expressing cells. Glucose stimulated reporter gene expression in these cells, suggesting that glucose-responsive elements mere included within the proximal region of the promoter. A dose-dependent effect of glucose on GLUT2 expression was observed over 10 mM glucose irrespective of the hexokinase isozyme (glucokinase K(m) 16 mM; hexokinase I K(m) 0.01 mM) present in the cell type used. This suggests that the correlation between extracellular glucose and GLUT2 mRNA concentrations is simply a reflection of an activation of glucose metabolism. The mediators and the mechanism responsible for this response remain to be determined. In conclusion, glucose metabolism is required for the proper induction of the GLUT2 gene in the liver and this effect is transcriptionally regulated.

Panel 2D Summary: Ag1681 The expression of the CG56151-01 gene appears to be highest in a sample of normal liver tissue adjacent to a colon cancer metastasis (CT=24.6). In addition, there is substantial expression in both normal and malignant liver tissue. This restricted pattern of expression in liver derived tissue is consistent with expression in the previous panels. Thus, the expression of this gene could be used to distinguish liver derived tissue from other samples in the panel. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be beneficial in the treatment of liver cancer.

Panel 5D Summary: Ag1681 The expression pattern of the CG56151-01 gene, a Glut2 homolog, is limited to a liver cell line (HepG2) and small intestines. The presence of this isoform in the intestines may indicate an important role in glucose uptake from the digestive tract. Please refer to panel 1.4 for a further discussion of utility of this gene in metabolic disease.

Panel 1.3D Summary: Ag1688 Expression of the CG56155-01 gene, a plasma kallikrein homolog, is significantly higher in liver (CTs=28) than in any other sample on this panel. Thus, expression of this gene could be used as a marker of liver tissue. Plasma kallikrein is a serine protease that, among other roles, plays a part in blood coagulation, fibrinolysis, and complement activation and has been implicated in adipose differentiation by remodelling of the fibronectin-rich ECM of preadipocytes. Therefore, an antagonist to this gene product may be beneficial in the treatment of obesity.

The purpose of this study was to examine the role of the plasminogen system in the development of adipose tissue. Plasminogen binding capacity was determined in differentiated and undifferentiated cells from adipose tissue of plasminogen deficient mice and 3T3 cells, a well-characterized tissue culture model. In 3T3 cells, plasminogen binding was fivefold higher in differentiated cells compared to the undifferentiated cells. Inhibition of binding by carboxyl-terminal lysine analogs was similar for the differentiated and undifferentiated cells with tranexamic acid>EACA>lysine. The binding of plasminogen was concentration-dependent and approaches saturation in the both cell types. The number of plasminogen binding sites was tenfold higher in the differentiated compared to the undifferentiated cells. In isolated mature fat cells and stromal cell cultures from mouse adipose tissue, plasminogen binding was also higher in the differentiated mature fat cells and differentiated stromal cells compared to undifferentiated stromal cells. Plasminogen binding was elevated in the differentiated cells from the Plg−/− mice compared to cells from the WT mice. These results suggest that the plasminogen system plays an important role in adipose tissue development. Copyright 2001 Academic Press.

Here we show that plasma kallikrein (PKal) mediates a plasminogen (Plg) cascade in adipocyte differentiation. Ecotin, an inhibitor of serine proteases, inhibits cell-shape change, adipocyte-specific gene expression, and lipid accumulation during adipogenesis in culture. Deficiency of Plg, but not of urokinase or tissue-type plasminogen activator, suppresses adipogenesis during differentiation of 3T3-L1 cells and mammary-gland involution. PKal, which is inhibited by ecotin, is required for adipose conversion Plg activation and 3T3-L1 differentiation. Human plasma lacking PKal does not support differentiation of 3T3-L1 cells. PKal is therefore a physiological regulator that acts in the Plg cascade during adipogenesis

We propose that the Plg cascade fosters adipocyte differentiation by degradation of the fibronectin-rich preadipocyte stromal matrix.

Panel 2D Summary: Ag1688 The expression of the CG56155-01 gene appears to be highest in a sample derived from a sample of normal liver tissue adjacent to a metastatic colon cancer CT=26.2). In addition, there is substantial expression in other samples of normal liver, and to a much lesser degree, malignant liver tissue. This liver specific expression is consistent with the expression seen in Panel 1.3D. Thus, the expression of this gene could be used to distinguish liver derived tissue from the toher samples in the panel, and more specifically the expression of this gene could be used to distinguish normal liver from malignant liver tissue. Moreover, therapeutic modulation of this gene, through the use of small molecule drugs, protein therapeutics or antibodies might be of benefit in the treatment of liver cancer.

Panel 5 Islet Summary: Ag1688 Expression of the CG56155-01 gene is limited to pancreatic islets and small intestines. Please see Panel 1.3 for discussion of utility of this gene in metabolic disease.

Example 3 SNP Analysis of SECX and/or NOVX Clones

SeqCallingTM Technology: cDNA was derived from various human samples representing multiple tissue types, normal and diseased states, physiological states, and developmental states from different donors. Samples were obtained as whole tissue, cell lines, primary cells or tissue cultured primary cells and cell lines. Cells and cell lines may have been treated with biological or chemical agents that regulate gene expression for example, growth factors, chemokines, steroids. The cDNA thus derived was then sequenced using CuraGen's proprietary SeqCalling technology. Sequence traces were evaluated manually and edited for corrections if appropriate. cDNA sequences from all samples were assembled with themselves and with public ESTs using bioinformatics programs to generate CuraGen's human SeqCalling database of SeqCalling assemblies. Each assembly contains one or more overlapping cDNA sequences derived from one or more human samples. Fragments and ESTs were included as components for an assembly when the extent of identity with another component of the assembly was at least 95% over 50 bp. Each assembly can represent a gene and/or its variants such as splice forms and/or single nucleotide polymorphisms (SNPs) and their combinations

Variant sequences are included in this application. A variant sequence can include a single nucleotide polymorphism (SNP). A SNP can, in some instances, be referred to as a “cSNP” to denote that the nucleotide sequence containing the SNP originates as a cDNA. A SNP can arise in several ways. For example, a SNP may be due to a substitution of one nucleotide for another at the polymorphic site. Such a substitution can be either a transition or a transversion. A SNP can also arise from a deletion of a nucleotide or an insertion of a nucleotide, relative to a reference allele. In this case, the polymorphic site is a site at which one allele bears a gap with respect to a particular nucleotide in another allele. SNPs occurring within genes may result in an alteration of the amino acid encoded by the gene at the position of the SNP. Intragenic SNPs may also be silent, however, in the case that a codon including a SNP encodes the same amino acid as a result of the redundancy of the genetic code. SNPs occurring outside the region of a gene, or in an intron within a gene, do not result in changes in any amino acid sequence of a protein but may result in altered regulation of the expression pattern for example, alteration in temporal expression, physiological response regulation, cell type expression regulation, intensity of expression, stability of transcribed message.

Method of novel SNP Identification: SNPs are identified by analyzing sequence assemblies using CuraGen's proprietary SNPTool algorithm. SNPTool identifies variation in assemblies with the following criteria: SNPs are not analyzed within 10 base pairs on both ends of an alignment; Window size (number of bases in a view) is 10; The allowed number of mismatches in a window is 2; Minimum SNP base quality (PHRED score) is 23; Minimum number of changes to score an SNP is 2/assembly position. SNPTool analyzes the assembly and displays SNP positions, associated individual variant sequences in the assembly, the depth of the assembly at that given position, the putative assembly allele frequency, and the SNP sequence variation. Sequence traces are then selected and brought into view for manual validation. The consensus assembly sequence is imported into CuraTools along with variant sequence changes to identify potential amino acid changes resulting from the SNP sequence variation. Comprehensive SNP data analysis is then exported into the SNPCalling database.

Method of novel SNP Confirmation: SNPs are confirmed employing a validated method know as Pyrosequencing (Pyrosequencing, Westborough, Mass.). Detailed protocols for Pyrosequencing can be found in: Alderbom et al. Determination of Single Nucleotide Polymorphisms by Real-time Pyrophosphate DNA Sequencing. (2000). Genome Research. 10, Issue 8. August. 1249-1265. In brief, Pyrosequencing is a real time primer extension process of genotyping. This protocol takes double-stranded, biotinylated PCR products from genomic DNA samples and binds them to streptavidin beads. These beads are then denatured producing single stranded bound DNA. SNPs are characterized utilizing a technique based on an indirect bioluminometric assay of pyrophosphate (PPi) that is released from each dNTP upon DNA chain elongation. Following Klenow polymerase-mediated base incorporation, PPi is released and used as a substrate, together with adenosine 5′-phosphosulfate (APS), for ATP sulflirylase, which results in the formation of ATP. Subsequently, the ATP accomplishes the conversion of luciferin to its oxi-derivative by the action of luciferase. The ensuing light output becomes proportional to the number of added bases, up to about four bases. To allow processivity of the method dNTP excess is degraded by apyrase, which is also present in the starting reaction mixture, so that only dNTPs are added to the template during the sequencing. The process has been fully automated and adapted to a 96-well format, which allows rapid screening of large SNP panels. The DNA and protein sequences for the novel single nucleotide polymorphic variants are reported. Variants are reported individually but any combination of all or a select subset of variants are also included. In addition, the positions of the variant bases and the variant amino acid residues are underlined.
